safe_arch

Exposes arch-specific intrinsics as safe function.

The crate aims to be as minimal as possible. Each intrinsic gets a function or macro so that you can safely use it as directly as possible. Essentially no additional abstractions are provided, that's not the point of this crate. The goal is only to provide safety while getting in the way as little as possible.

All function and macro availability is done purely at compile time via #[cfg()] attributes on the various modules. If a CPU feature isn't enabled for the build then those functions or macros won't be available. If you'd like to determine what CPU features are available at runtime and then call different code accordingly, this crate is not for you.

See the crate docs for more details.

• Minimum Rust: The CI tests the crate against Stable 1.43.0. The doc-tests are known to require at least 1.43 because they use u32::MAX, f32::NAN, and similar short names for the common consts. You can probably build the crate without the doc tests on older compiler versions, possibly as far back as 1.31, but that's not officially supported.
