completable

A Future value that resolves once it's explicitly completed, potentially from a different thread or task, similar to Java's CompletableFuture.

Currently, this is implemented using the Mutex from the std crate.

Examples

Create an incomplete Completable and explicitly complete it with the completer:

let (future, completer) = Completable::<i32>::new();
completer.complete(5).unwrap();
assert_eq!(block_on(future), Ok(5));

Create an initially complete Completable that can be immediately resolved:

assert_eq!(block_on(Completable::new_completed(10)), Ok(10));
