yield_now

fn yield_now()

use task::{yield_now};

Lets other ready tasks run before the current one continues.

Useful in a long computation that does no IO, so it does not hold up the other tasks.

• scope: Runs body with a Scope for starting child tasks, and returns its value once body and every child have finished.
• sleep: Suspends the current task for at least ms milliseconds; other tasks run meanwhile.
• timeout: Runs body as a task and cancels it if it has not finished after ms milliseconds.
• shield: Runs body so that a cancel waits for it to finish instead of interrupting it.
• channel: Creates a channel that holds up to capacity values.
• blocking: Runs work on another OS thread and waits for its result; only the current task waits, the others keep running.
• blocking_with: Like blocking, passing arg to work (it is copied to the other thread, like thread::spawn(work, arg)).
• block_on: Resumes the coroutine handle until it is done and returns its completion value; values it yields are discarded.
