Macro try_join 

macro_rules! try_join {
    ($($tokens:tt)*) => { ... };
}

Waits for multiple fallible concurrent futures, returning when all complete successfully.

This macro provides a runtime-agnostic way to execute multiple async operations that return Result and wait for all of them to complete. If any operation fails, the error is returned immediately. When using the Tokio runtime, this delegates to tokio::try_join!. When using the simulator runtime, this uses the simulator’s implementation.

Examples

let (a, b) = switchy::unsync::try_join!(
    async { Ok::<_, std::io::Error>(1) },
    async { Ok::<_, std::io::Error>(2) },
)?;
assert_eq!(a, 1);
assert_eq!(b, 2);
