Expand description
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.
