A safe Rust async runtime.

Features

• forbid(unsafe_code)
• Depends only on std at runtime
• Good test coverage (>85%)

Limitations

• No fs module yet. async-fs is a fast async networking library that works well with Safina. It contains some unsafe code.
• net module has poor performance. async-net is a fast async networking library that works well with Safina. It contains some unsafe code.
• Not optimized

Examples

use std::sync::Arc;
use safina::executor::Executor;

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

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