Async Slot

Documentation | Github | Crate

An unbounded channel that only stores last value sent made for futures.

Features:

  1. Compacts memory (only last value is kept)
  2. Has poll_cancel and is_canceled
  3. Single-producer/single-consumer
  4. Never has backpressure (because value is just replaced)
  5. Replaced value can be recovered if using swap method.
  6. Sync, so if multi-producer is desired, Sender can be wrapped into an Arc/Rc and swap method is used to update value.
