Build Status](https://img.shields.io/github/actions/workflow/status/khonsulabs/justjson/rust.yml?branch=main)](https://github.com/khonsulabs/justjson/actions?query=workflow:Tests) 3 | [![HTML Coverage Report for `main` branch](https://khonsulabs.github.io/justjson/coverage/badge.svg)](https://khonsulabs.github.io/justjson/coverage/) 4 | [![Documentation](https://img.shields.io/badge/docs-main-informational)]($docs-base$) 5 | 6 | An efficient JSON [`Value`][value] crate for Rust. 7 | 8 | **This crate is thoroughly tested, but it's still very early in development. 9 | Feedback is greatly appreciated.** 10 | 11 | ## Why another JSON library? 12 | 13 | This library is for developers who: 14 | 15 | - Are working with JSON, but either don't want to or can't use `serde`. 16 | - Want to parse a JSON Value from a slice with minimal allocations. 17 | 18 | If neither of those situations apply to you, you should seriously consider using 19 | `serde` and [`serde-json`][serde-json] or [`simd-json`][simd-json]. 20 | 21 | What real-world case does this use case fit? Parsing [JSON-LD Compacted Document 22 | Form][json-ld] requires inspecting the JSON to find the `@context` field, and 23 | using the information within the `@context` field to interpret the rest of the 24 | document. This form of JSON-LD representation is used by 25 | [ActivityPub][activitypub], which is a protocol that power [the 26 | Fediverse][fediverse]. 27 | 28 | ## What makes JustJson interesting? 29 | 30 | The optimal use case for JustJson is when parsing an `&str` or `&[u8]`. When 31 | parsing either of these, the returned [`Value`][value] type is `Value<&str>`. All strings 32 | and numbers are kept in their original form in the [`JsonString`][string] and 33 | [`JsonNumber`][number] types. While they are kept in their original form, they 34 | are fully validated when parsed. **The net effect is significantly fewer 35 | allocations when parsing a JSON value.** 36 | 37 | [`JsonString`][string] implements `PartialEq<&str>`/`PartialCmp<&str>` such that 38 | if the `JsonString` contains escape sequences, the comparison is handled 39 | correctly. Each `JsonString` tracks its decoded length as well as whether any 40 | escapes are present, allowing this comparison to be very efficient. 41 | 42 | ```rust 43 | let json = justjson::JsonString::from_json("\"Hello, World!\"").unwrap(); 44 | assert_eq!(json, "Hello, World!"); 45 | ``` 46 | 47 | JustJson also offers an even faster method for parsing: [`Document`][document]. 48 | When parsing an array or an object into a `Value`, the parser doesn't know how 49 | large each array or object will be until it parses the rest of the object. 50 | `Document` builds a tree representing the JSON value in a single `Vec`, further 51 | reducing the number of allocations needed when parsing a document. 52 | 53 | This extra speed comes at the expense of an API that requires iteration to 54 | inspect the `Document`. 55 | 56 | ## Benchmarks 57 | 58 | You can run the benchmarks by executing `RUSTFLAGS="-C target-cpu=native" cargo 59 | bench -p benchmarks --all-features`. There currently is only a single benchmark, 60 | testing a small JSON payload in both pretty and compact representations. 61 | 62 | ```text 63 | small-pretty/justjson/str 64 | time: [802.34 ns 804.91 ns 807.35 ns] 65 | small-pretty/justjson/doc/str 66 | time: [603.15 ns 607.13 ns 611.21 ns] 67 | small-pretty/justjson/bytes 68 | time: [774.45 ns 775.84 ns 777.37 ns] 69 | small-pretty/justjson/doc/bytes 70 | time: [688.51 ns 696.55 ns 705.09 ns] 71 | small-pretty/serde-json/str 72 | time: [860.82 ns 862.12 ns 863.43 ns] 73 | small-pretty/serde-json/bytes 74 | time: [917.49 ns 920.17 ns 923.26 ns] 75 | small-pretty/simd-json/bytes 76 | time: [702.67 ns 704.71 ns 706.61 ns] 77 | small-pretty/json-deserializer/bytes 78 | time: [858.81 ns 861.37 ns 864.88 ns] 79 | 80 | small/justjson/str time: [736.80 ns 739.94 ns 743.56 ns] 81 | small/justjson/doc/str time: [611.54 ns 618.64 ns 625.15 ns] 82 | small/justjson/bytes time: [710.26 ns 711.53 ns 712.86 ns] 83 | small/justjson/doc/bytes 84 | time: [588.97 ns 594.66 ns 600.98 ns] 85 | small/serde-json/str time: [831.89 ns 833.17 ns 834.69 ns] 86 | small/serde-json/bytes time: [874.84 ns 876.26 ns 877.90 ns] 87 | small/simd-json/bytes time: [690.41 ns 691.48 ns 692.79 ns] 88 | small/json-deserializer/bytes 89 | time: [778.87 ns 779.85 ns 780.85 ns] 90 | ``` 91 | 92 | ## Usage of Unsafe Code 93 | 94 | This crate uses unsafe code only when converting from raw incoming data to UTF-8 95 | data. The parser fully verifies that the data is valid UTF-8 before these 96 | functions are used. 97 | 98 | ## `no_std` support 99 | 100 | By default, this crate enables the `std` feature, which adds support for Rust's 101 | standard library types. By disabling default features, this crate can be used in 102 | `no_std` projects. For example, in your Cargo.toml: 103 | 104 | ```toml 105 | [dependencies] 106 | justjson = { version = "*", default-features = false } 107 | ``` 108 | 109 | The [`Value`][value] type requires the `alloc` feature to be enabled. 110 | 111 | The [`Document`][document] type alias requires the `alloc` feature, but the 112 | [`GenericDocument`][generic-doc] type allows providing your own collection type. 113 | 114 | With the `heapless` feature enabled, the [`HeaplessDocument`][heapless-doc] type 115 | can be used to parse documents using the [heapless][heapless] crate's `Vec` type 116 | for storage. This enables parsing JSON in environments where the `alloc` crate 117 | isn't supported. 118 | 119 | [value]: $value$ 120 | [string]: $string$ 121 | [number]: $number$ 122 | [document]: $document$ 123 | [generic-doc]: $generic-document$ 124 | [heapless-doc]: $heapless-document$ 125 | [json-ld]: https://www.w3.org/TR/json-ld11/#compacted-document-form 126 | [fediverse]: https://en.wikipedia.org/wiki/Fediverse 127 | [activitypub]: https://www.w3.org/TR/activitypub/ 128 | [simd-json]: https://github.com/simd-lite/simd-json 129 | [serde-json]: https://github.com/serde-rs/json 130 | [heapless]: https://github.com/japaric/heapless 131 | -------------------------------------------------------------------------------- /.rustme/header.md: -------------------------------------------------------------------------------- 1 | # justjson 2 | -------------------------------------------------------------------------------- /CHANGELOG.md: -------------------------------------------------------------------------------- 1 | # Changelog 2 | 3 | All notable changes to this project will be documented in this file. 4 | 5 | The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/), 6 | and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). 7 | 8 | ## Unreleased 9 | 10 | ### Added 11 | 12 | - `JsonNumber` and `Value` now have these additional helpers for converting to 13 | native numeric types: 14 | 15 | - `as_u8` 16 | - `as_u16` 17 | - `as_u32` 18 | - `as_u64` 19 | - `as_u128` 20 | - `as_usize` 21 | - `as_i8` 22 | - `as_i16` 23 | - `as_i32` 24 | - `as_i64` 25 | - `as_i128` 26 | - `as_isize` 27 | - `as_f32` 28 | - `as_f64` 29 | 30 | - `JsonNumber::parse()` is a new function that uses a types `FromStr` 31 | implementation to parse the source of the numeric literal. 32 | 33 | ## v0.2.3 (2023-04-11) 34 | 35 | ### Changed 36 | 37 | - This crate's MSRV has been changed to 1.65. This is not a breaking change, 38 | however, as the crate never supported its advertised MSRV, and this new MSRV 39 | reflects what the true MSRV has always been. An additional CI pass was added 40 | to ensure the MSRV is always tested against. Thanks to @hr8 in #8 for 41 | reporting this. 42 | 43 | ### Added 44 | 45 | - `AnyStr::as_str()` has been added, which acts the same as 46 | `AsRef`/`Borrow`/`Deref`. 47 | - `JsonString::as_str()` has been added, which will return an `&str` to the 48 | contained string, if it doesn't contain escape sequences. If the string has 49 | escape sequences, None will be returned. 50 | - `Value::as_str()` has been added, which will return an `&str` to the contained 51 | string if the the `Value` is a `JsonString` that has no escape sequences. If 52 | the value is not a string or it has escape sequences, None will be returned. 53 | 54 | Thanks to @hr8 in #9 for requesting this. 55 | - `JsonString` now implements `Display` with the decoded representation. This 56 | also means that `ToString` is now implemented such that it produces a decoded 57 | string. 58 | - `Tokenizer` is a new low-level parsing type that provides basic tokenization. 59 | Thank you to @indietyp in #13 for refactoring the parser to expose this 60 | functionality! 61 | 62 | ## v0.2.2 (2023-02-02) 63 | 64 | ### Added 65 | 66 | - `JsonString` now implements `Ord`, `PartialOrd`, and `PartialOrd`, and 67 | `Hash`. 68 | - `Entry`, the type which `Object` is a collection of, is now exported. This was 69 | an oversight. Thanks to @PoiScript for reporting this in #6. 70 | - `Value::get(key)`, `Value::get_mut(key)`, and `Index<&str>`/`IndexMut<&str>` 71 | have been added to allow easier access to the contents of a `Value` when it is 72 | an object. Similar to most built-in collection types, the `Index` trait 73 | implementations will panic if the key is not found, but the `get` variants 74 | return an Option instead of panicking. 75 | - `Value::get_index(usize)`, `Value::get_index_mut(usize)`, and 76 | `Index`/`IndexMut` have been added to allow easier access to the 77 | contents of a `Value` when it is an array. Similar to most built-in collection 78 | types, the `Index` trait implementations will panic if the index is out of 79 | bounds, but the `get_index` variants return an Option instead of panicking. 80 | - `From<&str>`, `From`, `From>`, `From>`, and 81 | `From` have been implemented for `Value<'_>`. 82 | 83 | ## v0.2.1 (2023-01-25) 84 | 85 | This release contains no code changes. The `Cargo.toml` section for docs.rs has 86 | been updated in an attempt to enable `doc_auto_cfg`, which annotates what 87 | features flags are needed for any given item in the documentation. 88 | 89 | ## v0.2.0 (2023-01-25) 90 | 91 | ### Breaking Changes 92 | 93 | - `Value`, `Object`, `JsonNumber`, and `JsonString` have all changed from having 94 | a generic parameter to having a single lifetime parameter. Internally, all 95 | strings have been changed to `Cow<'_, str>` to allow for owned values to be 96 | injected into a `Value`/`Object` or `Vec>`. 97 | - `JsonString::source` has been removed from the public API. 98 | `JsonString::contents()` is now available to provide read-only access to the 99 | JSON-encoded representation. 100 | - `JsonNumber::source` has been removed from the public API. 101 | `JsonNumber::source()` is now available to provide read-only access to the 102 | JSON-encoded representation. 103 | - `JsonString` now internally can be a JSON-encoded string or a raw string, and 104 | it will encode or decode escape sequences on the fly as needed. This means 105 | adding a new raw &str that needs escaping will not actually incur extra 106 | allocations while rendering a Value back to JSON, as the encoding operation 107 | will occur during the write to the destination. 108 | - `Object::push()` has been removed, and its `Deref` implementation now targets 109 | `Vec>`. This allows all `Vec` methods to be used to access the 110 | contents of an Object, including its own `push()` function. 111 | - `ParseDelegate::Error` is a new associated type that is now able to be 112 | returned from most `ParseDelegate` functions as the Error type of the Result. 113 | Previously, most functions did not return a Result. 114 | 115 | Returning an error from a `ParseDelegate` function will stop parsing the 116 | underlying document immediately and return the error in 117 | `ErrorKind::ErrorFromDelegate`. 118 | 119 | ### Fixes 120 | 121 | - Escaped UTF16 surrogate pairs are properly handled. Previously, all surrogates 122 | were considered invalid unicode. 123 | - Leading `+` signs are no longer allowed on numbers. 124 | - Leading `0`s are now disallowed on negative numbers. 125 | 126 | ### Added 127 | 128 | - `JsonString::from(&str)` has been added to convert from a Rust string to its 129 | JSON-encoded form. 130 | - This crate now is `no_std` compatible. The `no_std` support is controlled by 131 | three feature flags: 132 | 133 | - `std`: Enabled by default, enables `alloc` automatically. 134 | - `alloc`: Uses the `alloc` crate for the `Document` and `Value` types. 135 | - `heapless`: Exports a new `HeaplessDocument` type that can be used in 136 | environments without `alloc`. 137 | 138 | Without any features enabled, only `Parser`, `GenericDocument`, `JsonString`, 139 | and `JsonNumber` are available to parse JSON. 140 | 141 | To enable `GenericDocument` to work with types other than `Vec` and 142 | `heapless::Vec`, `NodeCollection` can be implemented for other Vec-like types. 143 | 144 | ### Changed 145 | 146 | - `thiserror` has been removed from the dependencies in favor of manually 147 | implementing `std::error::Error`. This makes `justjson` dependency free 148 | without enabling extra feature flags. 149 | 150 | ## v0.1.1 (2023-01-20) 151 | 152 | ### Fixed 153 | 154 | - Fixed a panic when reporting an error during decoding of some invalid unicode 155 | escape sequences. 156 | 157 | ## v0.1.0 (2023-01-19) 158 | 159 | - Initial release 160 | -------------------------------------------------------------------------------- /CODE_OF_CONDUCT.md: -------------------------------------------------------------------------------- 1 | # Contributor Covenant Code of Conduct 2 | 3 | ## Our Pledge 4 | 5 | We as members, contributors, and leaders pledge to make participation in our 6 | community a harassment-free experience for everyone, regardless of age, body 7 | size, visible or invisible disability, ethnicity, sex characteristics, gender 8 | identity and expression, level of experience, education, socio-economic status, 9 | nationality, personal appearance, race, religion, or sexual identity 10 | and orientation. 11 | 12 | We pledge to act and interact in ways that contribute to an open, welcoming, 13 | diverse, inclusive, and healthy community. 14 | 15 | ## Our Standards 16 | 17 | Examples of behavior that contributes to a positive environment for our 18 | community include: 19 | 20 | * Demonstrating empathy and kindness toward other people 21 | * Being respectful of differing opinions, viewpoints, and experiences 22 | * Giving and gracefully accepting constructive feedback 23 | * Accepting responsibility and apologizing to those affected by our mistakes, 24 | and learning from the experience 25 | * Focusing on what is best not just for us as individuals, but for the 26 | overall community 27 | 28 | Examples of unacceptable behavior include: 29 | 30 | * The use of sexualized language or imagery, and sexual attention or 31 | advances of any kind 32 | * Trolling, insulting or derogatory comments, and personal or political attacks 33 | * Public or private harassment 34 | * Publishing others' private information, such as a physical or email 35 | address, without their explicit permission 36 | * Other conduct which could reasonably be considered inappropriate in a 37 | professional setting 38 | 39 | ## Enforcement Responsibilities 40 | 41 | Community leaders are responsible for clarifying and enforcing our standards of 42 | acceptable behavior and will take appropriate and fair corrective action in 43 | response to any behavior that they deem inappropriate, threatening, offensive, 44 | or harmful. 45 | 46 | Community leaders have the right and responsibility to remove, edit, or reject 47 | comments, commits, code, wiki edits, issues, and other contributions that are 48 | not aligned to this Code of Conduct, and will communicate reasons for moderation 49 | decisions when appropriate. 50 | 51 | ## Scope 52 | 53 | This Code of Conduct applies within all community spaces, and also applies when 54 | an individual is officially representing the community in public spaces. 55 | Examples of representing our community include using an official e-mail address, 56 | posting via an official social media account, or acting as an appointed 57 | representative at an online or offline event. 58 | 59 | ## Enforcement 60 | 61 | Instances of abusive, harassing, or otherwise unacceptable behavior may be 62 | reported to the community leaders responsible for enforcement at 63 | moderators@khonsulabs.com. 64 | All complaints will be reviewed and investigated promptly and fairly. 65 | 66 | All community leaders are obligated to respect the privacy and security of the 67 | reporter of any incident. 68 | 69 | ## Enforcement Guidelines 70 | 71 | Community leaders will follow these Community Impact Guidelines in determining 72 | the consequences for any action they deem in violation of this Code of Conduct: 73 | 74 | ### 1.

Parsing [JSON-LD Compacted Document 24 | Form][json-ld] requires inspecting the JSON to find the `@context` field, and 25 | using the information within the `@context` field to interpret the rest of the 26 | document. This form of JSON-LD representation is used by 27 | [ActivityPub][activitypub], which is a protocol that power [the 28 | Fediverse][fediverse]. 29 | 30 | ## What makes JustJson interesting? 31 | 32 | The optimal use case for JustJson is when parsing an `&str` or `&[u8]`. When 33 | parsing either of these, the returned [`Value`][value] type is `Value<&str>`. All strings 34 | and numbers are kept in their original form in the [`JsonString`][string] and 35 | [`JsonNumber`][number] types. While they are kept in their original form, they 36 | are fully validated when parsed. **The net effect is significantly fewer 37 | allocations when parsing a JSON value.** 38 | 39 | [`JsonString`][string] implements `PartialEq<&str>`/`PartialCmp<&str>` such that 40 | if the `JsonString` contains escape sequences, the comparison is handled 41 | correctly. Each `JsonString` tracks its decoded length as well as whether any 42 | escapes are present, allowing this comparison to be very efficient. 43 | 44 | ```rust 45 | let json = justjson::JsonString::from_json("\"Hello, World!\"").unwrap(); 46 | assert_eq!(json, "Hello, World!"); 47 | ``` 48 | 49 | JustJson also offers an even faster method for parsing: [`Document`][document]. 50 | When parsing an array or an object into a `Value`, the parser doesn't know how 51 | large each array or object will be until it parses the rest of the object. 52 | `Document` builds a tree representing the JSON value in a single `Vec`, further 53 | reducing the number of allocations needed when parsing a document. 54 | 55 | This extra speed comes at the expense of an API that requires iteration to 56 | inspect the `Document`. 57 | 58 | ## Benchmarks 59 | 60 | You can run the benchmarks by executing `RUSTFLAGS="-C target-cpu=native" cargo 61 | bench -p benchmarks --all-features`. There currently is only a single benchmark, 62 | testing a small JSON payload in both pretty and compact representations. 63 | 64 | ```text 65 | small-pretty/justjson/str 66 | time: [802.34 ns 804.91 ns 807.35 ns] 67 | small-pretty/justjson/doc/str 68 | time: [603.15 ns 607.13 ns 611.21 ns] 69 | small-pretty/justjson/bytes 70 | time: [774.45 ns 775.84 ns 777.37 ns] 71 | small-pretty/justjson/doc/bytes 72 | time: [688.51 ns 696.55 ns 705.09 ns] 73 | small-pretty/serde-json/str 74 | time: [860.82 ns 862.12 ns 863.43 ns] 75 | small-pretty/serde-json/bytes 76 | time: [917.49 ns 920.17 ns 923.26 ns] 77 | small-pretty/simd-json/bytes 78 | time: [702.67 ns 704.71 ns 706.61 ns] 79 | small-pretty/json-deserializer/bytes 80 | time: [858.81 ns 861.37 ns 864.88 ns] 81 | 82 | small/justjson/str time: [736.80 ns 739.94 ns 743.56 ns] 83 | small/justjson/doc/str time: [611.54 ns 618.64 ns 625.15 ns] 84 | small/justjson/bytes time: [710.26 ns 711.53 ns 712.86 ns] 85 | small/justjson/doc/bytes 86 | time: [588.97 ns 594.66 ns 600.98 ns] 87 | small/serde-json/str time: [831.89 ns 833.17 ns 834.69 ns] 88 | small/serde-json/bytes time: [874.84 ns 876.26 ns 877.90 ns] 89 | small/simd-json/bytes time: [690.41 ns 691.48 ns 692.79 ns] 90 | small/json-deserializer/bytes 91 | time: [778.87 ns 779.85 ns 780.85 ns] 92 | ``` 93 | 94 | ## Usage of Unsafe Code 95 | 96 | This crate uses unsafe code only when converting from raw incoming data to UTF-8 97 | data. The parser fully verifies that the data is valid UTF-8 before these 98 | functions are used. 99 | 100 | ## `no_std` support 101 | 102 | By default, this crate enables the `std` feature, which adds support for Rust's 103 | standard library types. By disabling default features, this crate can be used in 104 | `no_std` projects. For example, in your Cargo.toml: 105 | 106 | ```toml 107 | [dependencies] 108 | justjson = { version = "*", default-features = false } 109 | ``` 110 | 111 | The [`Value`][value] type requires the `alloc` feature to be enabled. 112 | 113 | The [`Document`][document] type alias requires the `alloc` feature, but the 114 | [`GenericDocument`][generic-doc] type allows providing your own collection type. 115 | 116 | With the `heapless` feature enabled, the [`HeaplessDocument`][heapless-doc] type 117 | can be used to parse documents using the [heapless][heapless] crate's `Vec` type 118 | for storage. This enables parsing JSON in environments where the `alloc` crate 119 | isn't supported. 120 | 121 | [value]: https://khonsulabs.github.io/justjson/main/justjson/enum.Value.html 122 | [string]: https://khonsulabs.github.io/justjson/main/justjson/struct.JsonString.html 123 | [number]: https://khonsulabs.github.io/justjson/main/justjson/struct.JsonNumber.html 124 | [document]: https://khonsulabs.github.io/justjson/main/justjson/doc/type.Document.html 125 | [generic-doc]: https://khonsulabs.github.io/justjson/main/justjson/doc/struct.GenericDocument.html 126 | [heapless-doc]: https://khonsulabs.github.io/justjson/main/justjson/doc/type.HeaplessDocument.html 127 | [json-ld]: https://www.w3.org/TR/json-ld11/#compacted-document-form 128 | [fediverse]: https://en.wikipedia.org/wiki/Fediverse 129 | [activitypub]: https://www.w3.org/TR/activitypub/ 130 | [simd-json]: https://github.com/simd-lite/simd-json 131 | [serde-json]: https://github.com/serde-rs/json 132 | [heapless]: https://github.com/japaric/heapless 133 | 134 | ## Open-source Licenses 135 | 136 | This project, like all projects from [Khonsu Labs](https://khonsulabs.com/), are 137 | open-source.

[![Documentation](https://img.shields.io/badge/docs-main-informational)](https://khonsulabs.github.io/justjson/main/justjson) 5 | 6 | An efficient JSON [`Value`][value] crate for Rust. 7 | 8 | **This crate is thoroughly tested, but it's still very early in development. 9 | Feedback is greatly appreciated.** 10 | 11 | ## Why another JSON library? 12 | 13 | This library is for developers who: 14 | 15 | - Are working with JSON, but either don't want to or can't use `serde`. 16 | - Want to parse a JSON Value from a slice with minimal allocations. 17 | 18 | If neither of those situations apply to you, you should seriously consider using 19 | `serde` and [`serde-json`][serde-json] or [`simd-json`][simd-json]. 20 | 21 | What real-world case does this use case fit? Parsing [JSON-LD Compacted Document 22 | Form][json-ld] requires inspecting the JSON to find the `@context` field, and 23 | using the information within the `@context` field to interpret the rest of the 24 | document. This form of JSON-LD representation is used by 25 | [ActivityPub][activitypub], which is a protocol that power [the 26 | Fediverse][fediverse]. 27 | 28 | ## What makes JustJson interesting? 29 | 30 | The optimal use case for JustJson is when parsing an `&str` or `&[u8]`. When 31 | parsing either of these, the returned [`Value`][value] type is `Value<&str>`. All strings 32 | and numbers are kept in their original form in the [`JsonString`][string] and 33 | [`JsonNumber`][number] types. While they are kept in their original form, they 34 | are fully validated when parsed. **The net effect is significantly fewer 35 | allocations when parsing a JSON value.** 36 | 37 | [`JsonString`][string] implements `PartialEq<&str>`/`PartialCmp<&str>` such that 38 | if the `JsonString` contains escape sequences, the comparison is handled 39 | correctly. Each `JsonString` tracks its decoded length as well as whether any 40 | escapes are present, allowing this comparison to be very efficient. 41 | 42 | ```rust 43 | let json = justjson::JsonString::from_json("\"Hello, World!\"").unwrap(); 44 | assert_eq!(json, "Hello, World!"); 45 | ``` 46 | 47 | JustJson also offers an even faster method for parsing: [`Document`][document]. 48 | When parsing an array or an object into a `Value`, the parser doesn't know how 49 | large each array or object will be until it parses the rest of the object. 50 | `Document` builds a tree representing the JSON value in a single `Vec`, further 51 | reducing the number of allocations needed when parsing a document. 52 | 53 | This extra speed comes at the expense of an API that requires iteration to 54 | inspect the `Document`. 55 | 56 | ## Benchmarks 57 | 58 | You can run the benchmarks by executing `RUSTFLAGS="-C target-cpu=native" cargo 59 | bench -p benchmarks --all-features`. There currently is only a single benchmark, 60 | testing a small JSON payload in both pretty and compact representations. 61 | 62 | ```text 63 | small-pretty/justjson/str 64 | time: [802.34 ns 804.91 ns 807.35 ns] 65 | small-pretty/justjson/doc/str 66 | time: [603.15 ns 607.13 ns 611.21 ns] 67 | small-pretty/justjson/bytes 68 | time: [774.45 ns 775.84 ns 777.37 ns] 69 | small-pretty/justjson/doc/bytes 70 | time: [688.51 ns 696.55 ns 705.09 ns] 71 | small-pretty/serde-json/str 72 | time: [860.82 ns 862.12 ns 863.43 ns] 73 | small-pretty/serde-json/bytes 74 | time: [917.49 ns 920.17 ns 923.26 ns] 75 | small-pretty/simd-json/bytes 76 | time: [702.67 ns 704.71 ns 706.61 ns] 77 | small-pretty/json-deserializer/bytes 78 | time: [858.81 ns 861.37 ns 864.88 ns] 79 | 80 | small/justjson/str time: [736.80 ns 739.94 ns 743.56 ns] 81 | small/justjson/doc/str time: [611.54 ns 618.64 ns 625.15 ns] 82 | small/justjson/bytes time: [710.26 ns 711.53 ns 712.86 ns] 83 | small/justjson/doc/bytes 84 | time: [588.97 ns 594.66 ns 600.98 ns] 85 | small/serde-json/str time: [831.89 ns 833.17 ns 834.69 ns] 86 | small/serde-json/bytes time: [874.84 ns 876.26 ns 877.90 ns] 87 | small/simd-json/bytes time: [690.41 ns 691.48 ns 692.79 ns] 88 | small/json-deserializer/bytes 89 | time: [778.87 ns 779.85 ns 780.85 ns] 90 | ``` 91 | 92 | ## Usage of Unsafe Code 93 | 94 | This crate uses unsafe code only when converting from raw incoming data to UTF-8 95 | data. The parser fully verifies that the data is valid UTF-8 before these 96 | functions are used. 97 | 98 | ## `no_std` support 99 | 100 | By default, this crate enables the `std` feature, which adds support for Rust's 101 | standard library types. By disabling default features, this crate can be used in 102 | `no_std` projects. For example, in your Cargo.toml: 103 | 104 | ```toml 105 | [dependencies] 106 | justjson = { version = "*", default-features = false } 107 | ``` 108 | 109 | The [`Value`][value] type requires the `alloc` feature to be enabled. 110 | 111 | The [`Document`][document] type alias requires the `alloc` feature, but the 112 | [`GenericDocument`][generic-doc] type allows providing your own collection type. 113 | 114 | With the `heapless` feature enabled, the [`HeaplessDocument`][heapless-doc] type 115 | can be used to parse documents using the [heapless][heapless] crate's `Vec` type 116 | for storage. This enables parsing JSON in environments where the `alloc` crate 117 | isn't supported. 118 | 119 | [value]: crate::Value 120 | [string]: crate::JsonString 121 | [number]: crate::JsonNumber 122 | [document]: crate::doc::Document 123 | [generic-doc]: crate::doc::GenericDocument 124 | [heapless-doc]: crate::doc::HeaplessDocument 125 | [json-ld]: https://www.w3.org/TR/json-ld11/#compacted-document-form 126 | [fediverse]: https://en.wikipedia.org/wiki/Fediverse 127 | [activitypub]: https://www.w3.org/TR/activitypub/ 128 | [simd-json]: https://github.com/simd-lite/simd-json 129 | [serde-json]: https://github.com/serde-rs/json 130 | [heapless]: https://github.com/japaric/heapless 131 | -------------------------------------------------------------------------------- /src/anystr.rs: -------------------------------------------------------------------------------- 1 | #[cfg(feature = "alloc")] 2 | use alloc::string::String; 3 | use core::borrow::Borrow; 4 | use core::hash::Hash; 5 | use core::ops::Deref; 6 | 7 | /// A string that can be either Owned or Borrowed. 8 | /// 9 | /// This type is similar to the standard library's Cow, but the `Owned` variant 10 | /// is only available when the `alloc` or `std` features are enabled. 11 | #[derive(Debug, Clone)] 12 | pub enum AnyStr<'a> { 13 | /// An owned String. 14 | #[cfg(feature = "alloc")] 15 | Owned(String), 16 | /// A borrowed string slice. 17 | Borrowed(&'a str), 18 | } 19 | 20 | impl<'a> AnyStr<'a> { 21 | /// Returns this string as a `str` reference. 22 | /// 23 | /// This function in general doesn't need to be called, as `AnyStr` 24 | /// implements `AsRef`, `Borrow`, and `Deref`.
