Module futures::task [−] [src]

Tools for working with tasks.

This module contains:

• Context, which provides contextual data present for every task, including a handle for waking up the task.

• Waker, a handle for waking up a task.

• LocalKey, a key for task-local data; you should use the task_local macro to set up such keys.

Tasks themselves are generally created by spawning a future onto an executor. However, you can manually construct a task by creating your own Context instance, and polling a future with it.

The remaining types and traits in the module are used for implementing executors or dealing with synchronization issues around task wakeup.
