Required Methods

fn take_resumed_scheduler( &self, context: SchedulingContext, result_with_timings: ResultWithTimings, ) -> InstalledSchedulerBox

fn register_timeout_listener(&self, timeout_listener: TimeoutListener)

Registers an opaque timeout listener.

This method and the passed struct called TimeoutListener are very opaque by purpose. Specifically, it doesn’t provide any way to tell which listener is semantically associated to which particular scheduler. That’s because proper unregistration is omitted at the timing of scheduler returning to reduce latency of the normal block-verification code-path, relying on eventual stale listener clean-up by solScCleaner.

Provided Methods

fn take_scheduler(&self, context: SchedulingContext) -> InstalledSchedulerBox

A very thin wrapper of Self::take_resumed_scheduler to take a scheduler from this pool for a brand-new bank.
