About

Wirm is a light-weight, easy-to-use, Rust Library for performing WebAssembly transformations. It uses wasmparser and wasm_encoder to parse and encode Wasm components/modules and maintains its own Intermediate Representation.

Cargo Features

Parallel Processing

Wirm supports parallel processing during module parsing and encoding to improve performance for modules with many functions. This feature uses rayon to process function bodies concurrently.

Enable the feature by adding the parallel feature to your Cargo.toml:

[dependencies]
wirm = { version = "1.1.0", features = ["parallel"] }

Environment Setup
