Macro completion_stream 

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

Available on crate features macro and std only.

A bang macro to generate completion async streams.

These async streams evaluate to a CompletionStream, and you can .await CompletionFutures inside of them. You can return values using a yield expression. The ? operator works in the stream if it yields an Option or Result - if an error occurs the stream will yield that single error and then exit.

Examples

use completion::{completion_stream, CompletionStreamExt};

let stream = completion_stream! {
    for i in 0..3 {
        yield i;
    }
};

pin!(stream);

assert_eq!(stream.next().await, Some(0));
assert_eq!(stream.next().await, Some(1));
assert_eq!(stream.next().await, Some(2));
assert_eq!(stream.next().await, None);
