Crate sleep

Provides APIs for tasks to sleep for specified time durations.

Key functions:

• The sleep function delays the current task for a given number of ticks.
• The sleep_until function delays the current task until a specific moment in the future.
• The [sleep_periodic] function allows for tasks to be delayed for periodic intervals of time and can be used to implement a period task.

TODO: use regular time-keeping abstractions like Duration and Instant.

Modules

future

Asynchronous sleep methods that operate on wakers.

Structs

Duration

A Duration type to represent a span of time, typically used for system timeouts.

Functions

sleep

Blocks the current task by putting it to sleep for duration ticks.

sleep_until

Blocks the current task by putting it to sleep until a specific tick count is reached, given by resume_time.

unblock_sleeping_tasks

Remove all tasks that have been delayed but are able to be unblocked now, the current tick count is provided by the system’s interrupt tick count.
