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).
