Enum SchedulerStatus

pub enum SchedulerStatus {
    Unavailable,
    Active(InstalledSchedulerBox),
    Stale(InstalledSchedulerPoolArc, ResultWithTimings),
}

Variants

Unavailable

Unified scheduler is disabled or installed scheduler is consumed by InstalledScheduler::wait_for_termination. Note that transition to Self::Unavailable from {Self::Active, Self::Stale} is one-way (i.e. one-time) unlike Self::Active <=> Self::Stale below. Also, this variant is transiently used as a placeholder internally when transitioning scheduler statuses, which isn’t observable unless panic is happening.

Active(InstalledSchedulerBox)

Scheduler is installed into a bank; could be running or just be waiting for additional transactions. This will be transitioned to Self::Stale after certain time (i.e. solana_unified_scheduler_pool::DEFAULT_TIMEOUT_DURATION) has passed if its bank hasn’t been frozen since installed.

Stale(InstalledSchedulerPoolArc, ResultWithTimings)

Scheduler has yet to freeze its associated bank even after it’s taken too long since installed, resulting in returning the scheduler back to the pool. Later, this can immediately (i.e. transparently) be transitioned to Self::Active as soon as there’s new transaction to be executed (= BankWithScheduler::schedule_transaction_executions is called, which internally calls BankWithSchedulerInner::with_active_scheduler to make the transition happen).
