Struct Chronon 

pub struct Chronon {
    pub store: Arc<dyn SchedulerStore>,
    pub scheduler: Arc<Scheduler>,
    pub executor: Arc<Executor>,
    pub coordinator: CoordinatorService,
    pub deployment: DeploymentShape,
    /* private fields */
}

Assembled Chronon runtime: store, scheduler, executor, and deployment loops.

Built via ChrononBuilder. Hosts typically spawn Chronon::run on a background task and call Chronon::shutdown on exit.

Fields

store: Arc<dyn SchedulerStore>

Shared persistence for jobs, runs, partitions, and workers.

scheduler: Arc<Scheduler>

Tick engine and partition assigner handle.

executor: Arc<Executor>

Script registry and async dispatch.

coordinator: CoordinatorService

Job/run CRUD facade over Self::store.

deployment: DeploymentShape

Deployment shape selected at build time.

Implementations

impl Chronon

pub fn shutdown(&self)

Signal all runtime loops to stop.

pub fn shutdown_handle(&self) -> Arc<Notify>

Shared shutdown signal for background Self::run tasks (testkit / host wiring).

pub async fn run(&mut self) -> Result<()>

Run deployment loops until Self::shutdown is called.

Returns an error for DeploymentShape::RemoteClient because no local loops apply.

pub async fn tick_once(&self) -> Result<TickResult>

Advance the scheduler by one tick (tests and manual stepping).

pub fn coordinator_service(&self) -> &CoordinatorService

Job and run CRUD for HTTP handlers and host integration.

pub fn executor(&self) -> &Executor

Script executor (registry + dispatch).
