Module zerocopy_channel

Source
Expand description

A zero-copy queue for sending values between asynchronous tasks.

It can be used concurrently by a producer (sender) and a consumer (receiver), i.e. it is an “SPSC channel”.

This queue takes a Mutex type so that various targets can be attained. For example, a ThreadModeMutex can be used for single-core Cortex-M targets where messages are only passed between tasks running in thread mode. Similarly, a CriticalSectionMutex can also be used for single-core targets where messages are to be passed from exception mode e.g. out of an interrupt handler.

This module provides a bounded channel that has a limit on the number of messages that it can store, and if this limit is reached, trying to send another message will result in an error being returned.

Structs§

  • A bounded zero-copy channel for communicating between asynchronous tasks with backpressure.
  • Receive-only access to a Channel.
  • Send-only access to a Channel.
