Implementations

impl TaskManager

pub(crate) fn new( sender: Option<ScriptEventLoopSender>, pipeline_id: PipelineId, shared_canceller: Option<TaskCanceller>, ) -> Self

pub(crate) fn pipeline_id(&self) -> PipelineId

pub(crate) fn sender(&self) -> Ref<'_, Option<ScriptEventLoopSender>>

pub(crate) fn canceller(&self, name: TaskSourceName) -> TaskCanceller

pub(crate) fn set_sender(&self, sender: Option<ScriptEventLoopSender>)

Update the sender for this TaskSource. This is used by dedicated workers, which only have a sender while handling messages (as their sender prevents the main thread Worker object from being garbage collected).

pub(crate) fn cancel_all_tasks_and_ignore_future_tasks(&self)

Cancel all queued but unexecuted tasks and ignore all subsequently queued tasks.

pub(crate) fn cancel_pending_tasks_for_source( &self, task_source_name: TaskSourceName, )

Cancel all queued but unexecuted tasks for the given task source, but subsequently queued tasks will not be ignored.
