# `wasmparser`: A WebAssembly Binary Parser
**A [Bytecode Alliance](https://bytecodealliance.org/) project**
[](https://crates.io/crates/wasmparser)
[](https://docs.rs/wasmparser/)
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`](https://docs.rs/wasmparser/latest/wasmparser/struct.Parser.html)
using
[`Parser::new`](https://docs.rs/wasmparser/latest/wasmparser/struct.Parser.html#method.new)
and then follow the examples documented for
[`Parser::parse`](https://docs.rs/wasmparser/latest/wasmparser/struct.Parser.html#method.parse)
or
[`Parser::parse_all`](https://docs.rs/wasmparser/latest/wasmparser/struct.Parser.html#method.parse_all).
