Owasm-std
Oasis WASM contracts standard library for Rust
owasm-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
[]
= "0.10"
Test owasm-std with
cargo test --features=test
The crate is supposed to be used on nightly Rust only, until the custom allocator api stablizes in Rust.
no_std
owasm-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 "owasm-test" to support testing of contracts' internal logic.
