The new wasmparser API provides dedicated reader types for each section type, which significantly simplifies the code. This also changes WasmError::from_binary_reader_error into a From trait so that we don't have to do .map_err(from_binary_reader_error) throughout the code.

//! 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).
