//! Performs translation from a wasm module in binary format to the in-memory form
//! of Cranelift IR. More particularly, it translates the code of all the functions bodies and
//! interacts with an environment implementing the
//! [`ModuleEnvironment`](trait.ModuleEnvironment.html)
//! trait to deal with tables, globals and linear memory.
//!
//! The crate provides a `DummyEnvironment` struct that will allow to translate the code of the
//! functions but will fail at execution.
//!
//! The main function of this module is [`translate_module`](fn.translate_module.html).
