Rustler

Rustler is a library for writing Erlang NIFs in safe Rust code. That means there should be no ways to crash the BEAM (Erlang VM). The library provides facilities for generating the boilerplate for interacting with the BEAM, handles encoding and decoding of Erlang terms, and catches rust panics before they unwind into C. The library provides functionality for both Erlang and Elixir, however Elixir is favored as of now. The code you write in a Rust NIF should never be able to crash the BEAM. Decoding and encoding rust values into Erlang terms is as easy as a function call. Making a Rust struct encodable and decodable to Erlang or Elixir can be done with a single attribute. Enables you to safely pass a reference to a Rust struct into Erlang code. The struct will be automatically dropped when it's no longer referenced.
