Low-level WebAssembly format library.
Add to Cargo.toml
endencies]
ty-wasm = "0.31"
and then
rn crate parity_wasm;
module = parity_wasm::deserialize_file("./res/cases/v1/hello.wasm").unwrap();
rt!(module.code_section().is_some());
code_section = module.code_section().unwrap(); // Part of the module with functions code
tln!("Function count in wasm file: {}", code_section.bodies().len());
parity-wasm
supports full wabt testsuite (https://github.com/WebAssembly/testsuite), running asserts that invloves deserialization.
To run testsuite:
wabt
(since parity-wasm builds it internally using wabt-rs
, see https://github.com/WebAssembly/wabt)git submodule update --init --recursive
)cargo test --release --manifest-path=spec/Cargo.toml
Decoder can be fuzzed with cargo-fuzz
using wasm-opt
(https://github.com/WebAssembly/binaryen):
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
cratesThis crate has a feature, std
, that is enabled by default. To use this crate
in a no_std
context, add the following to your Cargo.toml
:

ty-wasm = { version = "0.31", default-features = false }
Until allocator api is stabilized, this type of use is limited to nightly Rust.
