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 [Mutex][parking_lot::Mutex] from the [parking_lot] crate.

Examples

Create an incomplete [ControlledFuture] and explicitly complete it with the completer:

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

Create an initially complete [ControlledFuture] that can be immediately resolved:

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