Note: This was forked from https://github.com/paritytech/parity-wasm as this repo is archived and has issues needing addressed. It is recommended that published version of 0.45.0 parity-wasm not be used.
Low-level WebAssembly format library.
Add to Cargo.toml
[dependencies]
casper-wasm = "0.46"
and then
let module = casper_wasm::deserialize_file("./res/cases/v1/hello.wasm").unwrap();
assert!(module.code_section().is_some());
let code_section = module.code_section().unwrap(); // Part of the module with functions code
println!("Function count in wasm file: {}", code_section.bodies().len());
casper-wasm
supports full wasm testsuite, running asserts that involves deserialization.
To run testsuite:
git submodule update --init --recursive
)cargo test --release --workspace
Decoder can be fuzzed with cargo-fuzz
using wasm-opt
:
binaryen
and cargo-fuzz
(cmake
and a C++11 toolchain)git submodule update --init --recursive
)cargo fuzz
subcommand with cargo install cargo-fuzz
cargo fuzz
uses a rust compiler plugin: rustup override set nightly
cargo fuzz run deserialize
no_std
