About this package

A simple event-driven library for parsing WebAssembly binary files.

wasmparser: A WebAssembly Binary Parser

A Bytecode Alliance project

A simple, event-driven library for parsing WebAssembly binary files (or streams).

The library reports events as they happen and only stores parsing information for a brief period of time, making it fast and memory-efficient. The event-driven model, however, has some drawbacks. If you need random access to the entire WebAssembly data-structure, this is not the right library for you. You could however, build such a data-structure using this library.

To get started, create a Parser using Parser::new and then follow the examples documented for Parser::parse or Parser::parse_all.
