| |
| - [Accept `const_fn` attribute with no arguments and functions without `const` keyword.](https://github.com/taiki-e/const_fn/pull/34) |
| This allows `const_fn` to be used as an optional dependency. |
| |
| ```rust |
| #[cfg_attr(feature = "...", const_fn::const_fn)] |
| pub fn func() { |
| /* ... */ |
| } |
| ``` |
| |
| ## [0.4.3] - 2020-11-02 |
| |
| - [`const_fn` no longer fails to compile if unable to determine rustc version. Instead, it now displays a warning.](https://github.com/taiki-e/const_fn/pull/31) |
| |
| - [`const_fn` no longer relies on debug print format.](https://github.com/taiki-e/const_fn/pull/30) |
| |
| ## [0.4.2] - 2020-08-31 |
| |
| - [Improve error messages when failed to parse version information.](https://github.com/taiki-e/const_fn/pull/26) |

| |
| ## [0.4.1] - 2020-08-25 |

| ## [0.4.0] - 2020-08-25 |
| |
| - [Add support for version-based code generation.](https://github.com/taiki-e/const_fn/pull/17) The following conditions are available: |
| |
| ```rust |
| use const_fn::const_fn; |
| |
| // function is `const` on specified version and later compiler (including beta and nightly) |
| #[const_fn("1.36")] |
| pub const fn version() { |
| /* ... */ |
| } |
| |
| // function is `const` on nightly compiler (including dev build) |
| #[const_fn(nightly)] |
| pub const fn nightly() { |
| /* ... */ |
| } |
| |
| // function is `const` if `cfg(...)` is true |
| #[const_fn(cfg(...))] |
| pub const fn cfg() { |
| /* ... */ |
| } |
| |
| // function is `const` if `cfg(feature = "...")` is true |
| #[const_fn(feature = "...")] |
| pub const fn feature() { |
| /* ... */ |
| } |
| ``` |
