Actions Status

Implement a coroutine like C#'s yield return using Rust's async, await.

Exmaple

use yield_return::Yield;
let iter = Yield::new(|mut y| async move {
    y.ret(1).await;
    y.ret(2).await;
});
let list: Vec<_> = iter.collect();
assert_eq!(list, vec![1, 2]);

Compare with genawaiter

genawaiter already exists as a crate with the same purpose as this yield-return-rs.

Compared to genawaiter, yield-return-rs is very simple.

No dependencies, no macros, no unsafe code.

The code is short, with only one file, lib.rs. You can copy and paste the contents of lib.rs and use it as is.

Sync implementation

Generator support
