Tools included

The wasm-tools binary internally contains a number of subcommands for working with wasm modules. Many subcommands also come with Rust crates that can be use programmatically as well:

The wasm-tools CLI is primarily intended to be a debugging aid. The various subcommands all have --help explainer texts to describe more about their functionality as well.

Libraries

As mentioned above many of the tools of the wasm-tools CLI have libraries implemented in this repository as well. These libraries are:

• wasmparser - a library to parse WebAssembly binaries
• wat - a library to parse the WebAssembly text format
• wast - like wat, except provides an AST
• wasmprinter - prints WebAssembly binaries in their string form
• wasm-mutate - a WebAssembly test case mutator
• wasm-shrink - a WebAssembly test case shrinker
• wasm-smith - a WebAssembly test case generator
• wasm-encoder - a crate to generate a binary WebAssembly module

It's recommended to use the libraries directly rather than the CLI tooling when embedding into a separate project.
