parity-wasm

Rust WebAssembly format serializing/deserializing

along with (now deprecated) experimental interpreter

```rust

extern crate parity_wasm;

let module = paritywasm::deserializefile("./res/cases/v1/hello.wasm").unwrap(); assert!(module.codesection().issome());

let codesection = module.codesection().unwrap(); // Part of the module with functions code

println!("Function count in wasm file: {}", code_section.bodies().len()); ```

Interpreter and decoder supports full wabt testsuite (https://github.com/WebAssembly/testsuite), To run testsuite:

make sure you have all prerequisites to build wabt (since parity-wasm builds it internally using cmake, see https://github.com/WebAssembly/wabt)
checkout with submodules (git submodule update --init --recursive)
run cargo test --release --manifest-path=spec/Cargo.toml

Decoder can be fuzzed with cargo-fuzz using wasm-opt (https://github.com/WebAssembly/binaryen):

make sure you have all prerequisites to build binaryen and cargo-fuzz (cmake and a C++11 toolchain)
checkout with submodules (git submodule update --init --recursive)
install cargo fuzz subcommand with cargo install cargo-fuzz
set rustup to use a nightly toolchain, because cargo fuzz uses a rust compiler plugin: rustup override set nightly
run cargo fuzz run deserialize

Interpreter here is in deprecated state, new one (wasmi) can be found in separate crate: https://github.com/pepyakin/wasmi.
