Thin veneer over futures::channel::oneshot to fix use with select!

A bare [futures::channel::oneshot::Receiver] doesn’t work properly with futures::select!, because it has a broken FusedFuture implementation. (See futures-rs ticket #2455.)

Wrapping it up in a future::Fuse works around this, with a minor performance penalty.

Limitations

The API of this Receiver is rather more limited. For example, it lacks .try_recv().

Structs

  • Canceled
    Error returned from a [Receiver] when the corresponding [Sender] is dropped.

Functions

  • channel
    Return a fresh oneshot channel

Type Aliases

  • Receiver
    oneshot::Receiver that works properly with [futures::select!]
  • Sender
    oneshot::Sender type alias
