SessionRunRegistration

Struct SessionRunRegistration 

Source
pub struct SessionRunRegistration { /* private fields */ }
Expand description

Exact-run ownership lease returned by SessionActivationRouter::register_run.

The lease deliberately owns the safe-point receiver. Dropping it before the normal finalization handshake schedules exact-run cleanup, reconciles the durable activation watermark, and gives the router one chance to launch a successor. A stale lease can never clear a newer owner.

Implementations§

Source§

impl SessionRunRegistration

Source

pub fn notifications_mut(&mut self) -> &mut Receiver<u64>

Source

pub fn set_abort_cleanup<F, Fut>(&mut self, cleanup: F)
where F: FnOnce() -> Fut + Send + 'static, Fut: Future<Output = ()> + Send + 'static,

Run host-specific exact-reservation cleanup before an abandoned owner asks the router to reserve a successor.

Source

pub async fn begin_finalization(&mut self)

Source

pub async fn abandon(self)

Synchronously abandon this exact ownership lease.

Most cancellation paths can rely on Drop, which schedules the same cleanup. Startup paths that must return a truthful retryable response use this method so the runner slot and router owner are released before the response becomes observable. Cleanup runs in a detached owned task: cancelling the caller’s wait cannot strand an already-taken host cleanup closure or this router owner.

Source

pub async fn finish( self, admitted_generation: u64, ) -> Result<Option<SessionActivationDisposition>, SessionActivationError>

Complete the normal exact-owner handshake. The Drop fallback remains armed across the await and is disabled only after finalization returns.
