Module tokio::sync

Future-aware synchronization

This module is enabled with the sync feature flag.

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.
• lock, an asynchronous Mutex-like type.
• watch, a single-producer, multi-consumer channel that only stores the most recently sent value.

Modules

lock

An asynchronous Mutex-like type.

mpsc

A multi-producer, single-consumer queue for sending values across asynchronous tasks.

oneshot

A channel for sending a single message between asynchronous tasks.

watch

A single-producer, multi-consumer channel that only retains the last sent value.
