pwasm-std

Parity WASM contracts standard library for Rust

Build Status

Documentation

Parity Wasm Tutorial - a full fledged tutorial on how to write contracts in Webassembly for Kovan and other Wasm-enabled networks.

pwasm-std is a limited subset of the Rust standard library, along with a custom allocator which delegates the allocation to the runtime-defined externs.

Use

Just add a dependency

[dependencies]
pwasm-std = "0.9"

The crate is supposed to be used on nightly Rust only, until the custom allocator api stablizes in Rust.

no_std

pwasm-std is itself compiled with no_std and expected to be used within no_std-crates/binaries, since it defines lang_item-s on it's own, which will conflict with standard library.

But for test scenarios it can be compiled with feature "std" and auxiliary crate "pwasm-test" to support testing of contracts' internal logic.
