SLoC
The WebAssembly binary file decoder in Rust
A Bytecode Alliance project
The decoder library provides lightweight and fast decoding/parsing of WebAssembly binary files.
The other goal is minimal memory footprint. For this reason, there is no AST or IR of WebAssembly data.

Fuzzing
To fuzz test wasmparser.rs, switch to a nightly Rust compiler and install cargo-fuzz:
cargo install cargo-fuzz
Then, from the root of the repository, run:
cargo fuzz run parse
If you want to use files as seeds for the fuzzer, add them to fuzz/corpus/parse/
and restart cargo-fuzz.
