safina

This is a safe Rust async runtime.

Related crates: - safina-timer

Features

• forbid(unsafe_code)
• Depends only on std
• Good test coverage (100%)

Limitations

• Requires Rust nightly, for OnceCell and Wake trait
• Allocates memory
• Not optimized

Examples

rust safina::increase_threads_to(1); let (sender, receiver) = std::sync::mpsc::channel(); safina::spawn(Box::pin(async move { sender.send(()).unwrap(); })); receiver.recv().unwrap();

rust std::thread::spawn(safina::work); let result = safina::block_on(Box::pin(async { prepare_request().await?; execute_request().await }))?;
