libffi-sys-rs: Low-level Rust bindings for libffi

The C libffi library provides two main facilities: assembling calls to functions dynamically, and creating closures that can be called as ordinary C functions. This is an undocumented wrapper, generated by bindgen, intended as the basis for higher-level bindings, but you can see the C libffi documentation.

If you clone this repository in order to build the library, be sure to do a recursive clone, as we include C libffi as a submodule.

See the libffi crate for a higher-level API.

Usage

Building libffi-sys will build the libffi C library from github, which requires that you have a working make, C compiler, automake, autoconf, and texinfo first. It’s on crates.io, so you can add

[dependencies]
libffi-sys = "0.6.2"

to your Cargo.toml and

extern crate libffi_sys;

to your crate root.

If you clone from github, be sure to clone --recursive to get the C libffi.

This crate supports Rust version 1.20 and later.
