For example, getting the date when `miri` was available for the last 22 | time on `x86_64-apple-darwin` is as simple as running the following command: 23 | 24 | ``` 25 | $ curl https://rust-lang.github.io/rustup-components-history/x86_64-apple-darwin/miri 26 | 2019-06-08 27 | ``` 28 | 29 | More information (in a JSON format) can be found at a similar location with a `.json` suffix. This 30 | data will include at least the last date the package was available (if it ever was) and whether the 31 | package was available over a configurable range of dates. E.g., 32 | 33 | ``` 34 | $ curl https://rust-lang.github.io/rustup-components-history/x86_64-unknown-linux-gnu/miri.json 35 | {"2019-06-13":true,"2019-06-12":true,"2019-06-11":true,"2019-06-10":false,"2019-06-09":true,"2019-06-08":true,"2019-06-07":true,"last_available":"2019-06-13"} 36 | ``` 37 | 38 | Run the binary with a `--help` flag to see available options. 39 | 40 | More info is coming :) 41 | 42 | ### License 43 | 44 | Licensed under either of 45 | 46 | * Apache License, Version 2.0 ([LICENSE-APACHE](LICENSE-APACHE) or http://www.apache.org/licenses/LICENSE-2.0) 47 | * MIT license ([LICENSE-MIT](LICENSE-MIT) or http://opensource.org/licenses/MIT) 48 | 49 | at your option. 50 | 51 | #### Contribution 52 | 53 | Unless you explicitly state otherwise, any contribution intentionally submitted 54 | for inclusion in the work by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any 55 | additional terms or conditions. 56 | 57 | License: MIT/Apache-2.0 58 | -------------------------------------------------------------------------------- /library/Cargo.toml: -------------------------------------------------------------------------------- 1 | [package] 2 | name = "rustup-available-packages" 3 | version = "0.2.1" 4 | description = "Rustup tools state info" 5 | license = "MIT/Apache-2.0" 6 | keywords = ["rustup"] 7 | repository = "https://github.com/rust-lang/rustup-components-history" 8 | documentation = "https://docs.rs/rustup-available-packages/" 9 | readme = "README.md" 10 | edition = "2018" 11 | 12 | [dependencies] 13 | chrono = { version = "0.4.6", features = [ "serde" ] } 14 | thiserror = "1" 15 | log = "0.4.5" 16 | reqwest = { version = "0.11.2", features = ["blocking"] } 17 | serde = { version = "1", features = [ "derive" ] } 18 | toml = "0.5" 19 | -------------------------------------------------------------------------------- /library/README.md: -------------------------------------------------------------------------------- 1 | # rustup-available-packages 2 | 3 | [![Travis CI badge](https://api.travis-ci.com/rust-lang/rustup-components-history.svg?branch=master)](https://travis-ci.com/github/rust-lang/rustup-components-history) 4 | [![crates.io](https://img.shields.io/crates/v/rustup-available-packages.svg)](https://crates.io/crates/rustup-available-packages) 5 | [![docs.rs](https://docs.rs/rustup-available-packages/badge.svg)](https://docs.rs/rustup-available-packages) 6 | 7 | [[Release docs]](https://docs.rs/rustup-available-packages/) 8 | 9 | A library that helps you to find out which packages are available in your **rustup** tool for 10 | specific dates and targets. 11 | 12 | Suggestions and critiques are welcome! 13 | 14 | License: MIT/Apache-2.0 15 | -------------------------------------------------------------------------------- /library/src/availability.rs: -------------------------------------------------------------------------------- 1 | //!
