Module scheduler 

Background-job scheduler skeleton.

The host owns a single scheduler that drives every registered crate::traits::background::BackgroundJobProvider. This module ships the scheduler’s public API + persistent state record + a SchedulerPersistence trait. The host-side Tokio driver (crates/uni/src/scheduler.rs) wraps a loop that calls tick_at(SystemTime::now()), dispatches the returned jobs through the plugin registry, and forwards lifecycle transitions to the configured persistence backend.

Host-side scheduler skeleton.

SchedulerHandle

Cooperative-cancel handle handed to job implementations.

SchedulerJobRecord

Persistable record of a scheduled job’s state.

Enums

SchedulerJobStatus

Lifecycle state of one scheduled job.

SchedulerPersistenceError

Traits

SchedulerControl

Trait-object handle to a scheduler, for cross-crate callers that can’t depend on the concrete host-side SchedulerHost type.

SchedulerPersistence

Persistence backend for Scheduler job state.
