stdsimd - Rust's standard library SIMD components
=======

[![Travis-CI Status]][travis] [![Appveyor Status]][appveyor] [![Latest Version]][crates.io] [![docs]][docs.rs]

# Usage

`stdsimd` is now shipped with Rust's `std` library - its is part of `libcore`
and `libstd`.

The easiest way to use it is just to import it via `use std::arch`. 

The `std::arch` component for `x86` is available in stable Rust. The `std::arch`
components for other architectures and the `std::simd` component require nightly
Rust.

Using `stdsimd` master branch is not recommended. It requires nightly Rust, it
only works with particular Rust nightly versions, and it can (and does) break
often. If you need to use `stdsimd` master branch, you can add it to your
`Cargo.toml` as follows:

```toml
#[dependencies]
stdsimd = { git = "https://github.com/rust-lang-nursery/stdsimd.git" }
```

### Approach

The main goal is to expose APIs defined by *vendors* with the least amount of
abstraction possible. On x86, for example, the API should correspond to that
provided by `emmintrin.h`.
