A crate for creating [Erlang NIF modules](http://www.erlang.org/doc/man/erl_nif.html) in Rust.  This crate exposes the raw C NIF API which can be used directly or as a foundation for higher layer interface crates.  Supported under Unix and Windows.

See the [crate documention](https://docs.rs/erlang_nif-sys).

See examples of use:
 - [rust.mk](https://github.com/goertzenator/rust.mk) for a sample Rust NIF module.
 - [rebar3_rust](https://github.com/sdwolf/rebar3_rust) a rebar3 plugin inspired by `rust.mk` that helps integrate Rust code inside Erlang projects.
 - [Rustler](https://github.com/hansihe/Rustler)
 - [rustfromerl](https://github.com/sdwolf/rustfromerl) a demo project showing performance differences between Erlang code and a simmilar Rust NIF implementation.

Thanks go to Radosław Szymczyszyn for bootstrapping me on this Rust FFI adventure and providing the original [automatic bindings](https://github.com/lavrin/erlang-rust-nif/blob/master/rust_src/src/c.rs).
