rustler 0.27.0

//! Contains basic wrappers for the Erlang NIF API. Should not be used directly.
//!
//! This module should perform validation and make them (reasonably) safe and easy to
//! use from Rust. This module should try to be as non-opinionated as possible, and
//! should try to stick as close as possible to the original C API.
//!
//! Making the APIs nice to use from Rust should be done in the root `rustler` crate.
