Struct Stop 

pub struct Stop { /* private fields */ }

A cooperative stop, shared with whoever asked the loop to run.

Cloning is how the request travels: serve_until keeps one handle, the Ctrl-C listener and the web UI keep others, and every clone points at the same flag. There is no channel because there is nothing to send — the only message is “stop”, it is idempotent, and a flag cannot be missed by a receiver that was not listening yet.

A stop ends scheduler dispatch promptly. Its busy snapshot is observational: detached task workers keep their own lifetimes and ownership after this handle’s scheduler exits.

Implementations

impl Stop

pub fn new() -> Self

A stop nobody has asked for yet.

pub fn stop(&self)

Ask the loop to stop. Idempotent, and safe to call before the loop starts: the flag is checked before the first poll.

pub fn stopped(&self) -> bool

Has a stop been asked for?

pub fn finishing(&self) -> bool

Whether a requested scheduler retirement still has an active snapshot. Workers continue independently after the scheduler has retired.

pub fn park(&self, cause: ParkCause)

Ask the loop to stop and the run in flight to park at its next node boundary.

Unlike plain stop, explicit park asks workers to checkpoint at their existing safe boundaries. Binary replacement never needs a park.

pub fn parking(&self) -> bool

Has a park been asked for?

pub fn pause(&self) -> Pause

The pause handle to give a runner.

pub fn busy_now(&self) -> bool

Whether the scheduler’s latest snapshot contains active task workers.
