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.

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.
