A subset of the TurboTasks API that’s exposed to Backend implementations.

Required Methods

fn pin(&self) -> Arc<dyn TurboTasksBackendApi<B>>

fn get_fresh_persistent_task_id(&self) -> Unused<TaskId>

fn get_fresh_transient_task_id(&self) -> Unused<TaskId>

unsafe fn reuse_persistent_task_id(&self, id: Unused<TaskId>)

Safety

The caller must ensure that the task id is not used anymore.

unsafe fn reuse_transient_task_id(&self, id: Unused<TaskId>)

Safety

The caller must ensure that the task id is not used anymore.

fn schedule(&self, task: TaskId)

Schedule a task for execution.

fn schedule_backend_foreground_job(&self, job: B::BackendJob)

Schedule a foreground backend job for execution.

fn schedule_backend_background_job(&self, job: B::BackendJob)

Schedule a background backend job for execution.

Background jobs are not counted towards activeness of the system. The system is considered idle even with active background jobs.

fn program_duration_until(&self, instant: Instant) -> Duration

Returns the duration from the start of the program to the given instant.

fn is_idle(&self) -> bool

Returns true if the system is idle.

fn backend(&self) -> &B

Returns a reference to the backend.
