Struct TaskHandle

Source

pub struct TaskHandle<O>where
    O: Clone + Send + 'static,{
    pub id: Uuid,
    /* private fields */
}

Expand description

Handle returned to a caller after submitting a task to the pool.

result() awaits the final task output.
events() returns a broadcast receiver for intermediate Events.
cancel() requests cooperative cancellation.

Fields§

§id: Uuid

Unique identifier assigned to this task by the pool.

Implementations§

Source §

impl<O> TaskHandle<O>
where O: Clone + Send + 'static,

Source

pub async fn result(self) -> Result<O, AppError>

Await the final result of the task.

Source

pub fn events(&self) -> Receiver<Event<O>>

Get a new broadcast receiver for intermediate events.

Source

pub fn cancel(&self)

Signal the task to cancel.

Source

pub fn cancel_token(&self) -> CancellationToken

Clone the cancellation token so it can be stored separately (e.g., for cancelling after the handle is consumed by result()).
