core_arch - Rust's standard library core::arch module

![Travis-CI Status] ![Appveyor Status] ![Latest Version] ![docs]

The core::arch module implements architecture-dependent intrinsics (e.g. SIMD).

Usage

core::arch is available as part of libcore and it is re-exported by libstd. Prefer using it via core::arch or std::arch than via this crate. Unstable features are often available in nightly Rust via the feature(stdsimd).

Using core::arch via this crate requires nightly Rust, and it can (and does) break often. The only cases in which you should consider using it via this crate are:

• if you need to re-compile core::arch yourself, e.g., with particular target-features enabled that are not enabled for libcore/libstd. Note: if you need to re-compile it for a non-standard target, please prefer using xargo and re-compiling libcore/libstd as appropriate instead of using this crate.

• using some features that might not be available even behind unstable Rust features. We try to keep these to a minimum. If you need to use some of these features, please open an issue so that we can expose them in nightly Rust and you can use them from there.
