safina

A safe Rust async runtime.

Features

• forbid(unsafe_code)
• Depends only on std
• Good test coverage (>92%)

Limitations

• Building on stable requires the feature once_cell. This uses once_cell crate which contains some unsafe code. This is necessary until std::lazy::OnceCell is stable.
• Allocates memory. You can avoid allocations by using advanced functions, like safina_executor::spawn_unpin.
• Not optimized

Documentation

https://docs.rs/safina

safina_async_test has an #[async_test] macro for running async fn test functions.

Examples

let executor = safina::Executor::default();
let (sender, receiver) = std::sync::mpsc::channel();
executor.spawn(async move {
    sender.send(()).unwrap();
});
receiver.recv().unwrap();

let result = safina::block_on(async {
    prepare_request().await?;
    execute_request().await
})?;
