Asynchronous channels.

Like threads, concurrent tasks sometimes need to communicate with each other. This module contains two basic abstractions for doing so:

  • oneshot, a way of sending a single value from one task to another.
  • mpsc, a multi-producer, single-consumer channel for sending values between tasks, analogous to the similarly-named structure in the standard library.

All items are only available when the std or alloc feature of this library is activated, and it is activated by default.


  • A multi-producer, single-consumer queue for sending values across asynchronous tasks.
  • A channel for sending a single message between asynchronous tasks.
