Struct ShutdownHandle

Source 
pub struct ShutdownHandle(/* private fields */);
Expand description

Notifies a service about an upcoming shutdown.

This handle is returned by Controller::shutdown_handle.

Implementations§

Source§

impl ShutdownHandle

Source

pub fn get(&self) -> Option<Shutdown>

Returns the current shutdown state.

Source

pub async fn notified(&mut self) -> Shutdown

Wait for a shutdown.

This receives all shutdown signals since the Controller has been started, even before this shutdown handle has been obtained.

§Cancel safety

This method is cancellation safe and can be used in select!.

Source

pub async fn finished(self)

Wait for the shutdown and timeout to complete.

This waits for the first shutdown signal and then conditionally waits for the shutdown timeout. If the shutdown timeout is interrupted by another signal, this function resolves immediately.

§Cancel safety

This method is not cancel safe.
