# Rust bindings for SLEEF

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

> [SLEEF: SIMD Library for Evaluating Elementary Functions](https://sleef.org/) 

Note: Rust does not support `long double` (80-bit precision floating-point
types) and the SLEEF APIs that use it are not included in these bindings _yet_
(they _could_ probably be added to just handle `long double` as a bag of bytes**.

### Cargo features

* **dft** (default: disabled - equivalent to SLEEF's
  [`BUILD_DFT`](https://sleef.org/compile.xhtml) option): SLEEF also includes
  SIMD-vectorized and parallelized subroutines for discrete Fourier transform
  (DFT) with an API similar to FFTW.

### Platform support

This wrapper supports the following platforms, but CI is not properly set up for
all of them yet.

| Linux targets:                  | build     | run     |
