Enum CycleOutcome 

pub enum CycleOutcome {
    Continue,
    Suspend,
    Shutdown(ShutdownCause),
}

The result of one executor processing cycle.

The owner uses this value to decide when to run another cycle.

Variants

Continue

The executor has more work that it can do now.

Suspend

The executor cannot make more progress now.

Wait for a reason to run another cycle. A reason can be:

• The owner has enqueued new tasks.
• An I/O operation has completed.
• A component sends a wake signal through the owner_waker from ExecutorBuilder::owner_waker().

The owner can also run periodic cycles as a fallback for missed wake signals.

Shutdown(ShutdownCause)

The executor has completed graceful shutdown and owns no tasks.

Later cycles do no work and return Shutdown with the first shutdown cause.
