Struct vector_lib::shutdown::SourceShutdownCoordinator

pub struct SourceShutdownCoordinator { /* private fields */ }

Implementations§

§

impl SourceShutdownCoordinator

pub fn register_source( &mut self, id: &ComponentKey, internal: bool, ) -> (ShutdownSignal, impl Future<Output = ()>)

Creates the necessary Triggers and Tripwires for coordinating shutdown of this Source and stores them as needed. Returns the ShutdownSignal for this Source as well as a Tripwire that will be notified if the Source should be forcibly shut down.

pub fn takeover_source( &mut self, id: &ComponentKey, other: &mut SourceShutdownCoordinator, )

Takes ownership of all internal state for the given source from another ShutdownCoordinator.

§Panics

Panics if the other coordinator already had its triggers removed.

pub fn shutdown_all(self, deadline: Option<Instant>) -> impl Future<Output = ()>

Sends a signal to begin shutting down to all sources, and returns a future that resolves once all sources have either shut down completely, or have been sent the force shutdown signal. The force shutdown signal will be sent to any sources that don’t cleanly shut down before the given deadline.

§Panics

Panics if this coordinator has had its triggers removed (ie has been taken over with Self::takeover_source).

pub fn shutdown_source( &mut self, id: &ComponentKey, deadline: Instant, ) -> impl Future<Output = bool>

Sends the signal to the given source to begin shutting down. Returns a future that resolves when the source has finished shutting down cleanly or been sent the force shutdown signal. The returned future resolves to a bool that indicates if the source shut down cleanly before the given deadline. If the result is false then that means the source failed to shut down before deadline and had to be force-shutdown.

§Panics

Panics if this coordinator has had its triggers removed (ie has been taken over with Self::takeover_source).

pub fn shutdown_tripwire(&self) -> Pin<Box<dyn Future<Output = ()> + Send>>

Returned future will finish once all current sources have finished.
