Crate wasmparser

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

The parser library reports events as they happend and only stores parsing information for a brief period of time, making it very 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.

Structs

BinaryReader	A binary reader of the WebAssembly structures and types.
BinaryReaderError
BrTable	A br_table entries representation.
FuncType
GlobalType
Ieee32	An IEEE binary32 immediate floating point value, represented as a u32 containing the bitpattern.
Ieee64	An IEEE binary64 immediate floating point value, represented as a u64 containing the bitpattern.
LocalName
