23 |
24 | # Rationale
25 | #
26 | # We don't run clippy with --all-targets because then even --lib and --bins are compiled with
27 | # dev dependencies enabled, which does not match how they would be compiled by users.
28 | # A dev dependency might enable a feature that we need for a regular dependency,
29 | # and checking with --all-targets would not find our feature requirements lacking.
30 | # This problem still applies to cargo resolver version 2.
31 | # Thus we split all the targets into two steps, one with --lib --bins
32 | # and another with --tests --benches --examples.
33 | # Also, we can't give --lib --bins explicitly because then cargo will error on binary-only packages.
34 | # Luckily the default behavior of cargo with no explicit targets is the same but without the error.
35 | #
36 | # We use cargo-hack for a similar reason. Cargo's --workspace will do feature unification across
37 | # the whole workspace. While cargo-hack will instead check each workspace package separately.
38 | #
39 | # Using cargo-hack also allows us to more easily test the feature matrix of our packages.
40 | # We use --each-feature & --optional-deps which will run a separate check for every feature.
41 | #
42 | # We use cargo-nextest, which has a faster concurrency model for running tests.
43 | # However cargo-nextest does not support running doc tests, so we also have a cargo test --doc step.
44 | # For more information see https://github.com/nextest-rs/nextest/issues/16
45 | #
46 | # The MSRV jobs run only cargo check because different clippy versions can disagree on goals and
47 | # running tests introduces dev dependencies which may require a higher MSRV than the bare package.
48 | #
49 | # For no_std checks we target x86_64-unknown-none, because this target doesn't support std
50 | # and as such will error out if our dependency tree accidentally tries to use std.
51 | # https://doc.rust-lang.org/stable/rustc/platform-support/x86_64-unknown-none.html
52 | #
53 | # We don't save caches in the merge-group cases, because those caches will never be re-used (apart
54 | # from the very rare cases where there are multiple PRs in the merge queue).
55 | # This is because GitHub doesn't share caches between merge queues and the main branch.

5 | A library for working with UI events and input types.

13 |
14 |
15 |
16 | The UI Events library provides functionality for working with UI events and input types.
17 | This library follows and is inspired by the relevant W3C specifications.
18 |
19 | ## Minimum supported Rust Version (MSRV)
20 |
21 | This version of UI Events has been verified to compile with **Rust 1.73** and later.
22 |
23 | Future versions of UI Events might increase the Rust version requirement.
24 | It will not be treated as a breaking change and as such can even happen with small patch releases.
25 |
26 |
27 | Click here if compiling fails.
28 |
29 | As time has passed, some of UI Events' dependencies could have released versions with a higher Rust requirement.
30 | If you encounter a compilation issue due to a dependency and don't want to upgrade your Rust toolchain, then you could downgrade the dependency.
31 |
32 | ```sh
33 | # Use the problematic dependency's name and version
34 | cargo update -p package_name --precise 0.1.1
35 | ```

137 |
138 | 6. Trademarks. This License does not grant permission to use the trade

168 | or other liability obligations and/or rights consistent with this
169 | License. However, in accepting such obligations, You may act only
170 | on Your own behalf and on Your sole responsibility, not on behalf
171 | of any other Contributor, and only if You agree to indemnify,
172 | defend, and hold each Contributor harmless for any liability

27 |
28 | This crate bridges [`winit`]'s native input events (mouse, touch, keyboard, etc.)
29 | into the [`ui-events`] model.
30 |
31 | The primary entry point is [`WindowEventReducer`].

37 | ## Minimum supported Rust Version (MSRV)
38 |
39 | This version of UI Events for Winit has been verified to compile with **Rust 1.81** and later.
40 |
41 | Future versions of UI Events for Winit might increase the Rust version requirement.
42 | It will not be treated as a breaking change and as such can even happen with small patch releases.
43 |
44 |
45 | Click here if compiling fails.
46 |
47 | As time has passed, some of UI Events for Winit's dependencies could have released versions with a higher Rust requirement.
48 | If you encounter a compilation issue due to a dependency and don't want to upgrade your Rust toolchain, then you could downgrade the dependency.
49 |
50 | ```sh
51 | # Use the problematic dependency's name and version
52 | cargo update -p package_name --precise 0.1.1
53 | ```

5 | A library for working with UI events and input types.

15 |
16 |
20 |
21 |
23 |
24 |
25 | A cross-platform input event abstraction modeled after W3C UI Events specifications.
26 |
27 | Provides common vocabulary types for working with pointer events (mouse, touch, pen) and
28 | keyboard events in a platform-agnostic way. The crate aims to closely follow W3C standards
29 | while remaining practical for native application development.
30 |
31 | Includes support for:
32 |
33 | - Pointer events (down/move/up, pressure, tilt, etc.)
34 | - Keyboard events (key codes, modifiers, location)
35 |
36 | For integration with [`winit`], use the companion [`ui-events-winit`] adapter crate.
37 |
38 | ## Features
39 |
40 | - `std` (enabled by default): Use the Rust standard library.

46 |
47 | ## Minimum supported Rust Version (MSRV)
48 |
49 | This version of UI Events has been verified to compile with **Rust 1.73** and later.
50 | The `no_std` build of this library needs **Rust 1.81** and later.
51 |
52 | Future versions of UI Events might increase the Rust version requirement.
53 | It will not be treated as a breaking change and as such can even happen with small patch releases.
54 |
55 |
56 | Click here if compiling fails.
57 |
58 | As time has passed, some of UI Events' dependencies could have released versions with a higher Rust requirement.
59 | If you encounter a compilation issue due to a dependency and don't want to upgrade your Rust toolchain, then you could downgrade the dependency.
60 |
61 | ```sh
62 | # Use the problematic dependency's name and version
63 | cargo update -p package_name --precise 0.1.1
64 | ```

68 | ## Community

71 |
72 | Discussion of UI Events development happens in the [Linebender Zulip](https://xi.zulipchat.com/), specifically the [#general channel](https://xi.zulipchat.com/#narrow/channel/147921-general).

158 | incidental, or consequential damages of any character arising as a
159 | result of this License or out of the use or inability to use the
160 | Work (including but not limited to damages for loss of goodwill,
161 | work stoppage, computer failure or malfunction, or any and all
162 | other commercial damages or losses), even if such Contributor
163 | has been advised of the possibility of such damages.
164 |
165 | 9. Accepting Warranty or Additional Liability. While redistributing
166 | the Work or Derivative Works thereof, You may choose to offer,
167 | and charge a fee for, acceptance of support, warranty, indemnity,
168 | or other liability obligations and/or rights consistent with this
169 | License. However, in accepting such obligations, You may act only
170 | on Your own behalf and on Your sole responsibility, not on behalf
171 | of any other Contributor, and only if You agree to indemnify,
172 | defend, and hold each Contributor harmless for any liability
173 | incurred by, or claims asserted against, such Contributor by reason
174 | of your accepting any such warranty or additional liability.

25 | UI Theme is a Rust crate which ...
26 |
27 | ## Features
28 |
29 | - `std` (enabled by default): Use the Rust standard library.
30 |
31 |
32 |
33 | ## Minimum supported Rust Version (MSRV)
34 |
35 | This version of UI Theme has been verified to compile with **Rust 1.73** and later.
36 | The `no_std` build of this library needs **Rust 1.81** and later.
37 |
38 | Future versions of UI Theme might increase the Rust version requirement.
39 | It will not be treated as a breaking change and as such can even happen with small patch releases.
40 |
41 |
42 | Click here if compiling fails.
43 |
44 | As time has passed, some of UI Theme's dependencies could have released versions with a higher Rust requirement.
45 | If you encounter a compilation issue due to a dependency and don't want to upgrade your Rust toolchain, then you could downgrade the dependency.
46 |
47 | ```sh
48 | # Use the problematic dependency's name and version
49 | cargo update -p package_name --precise 0.1.1
50 | ```
