Trait TaskResultHandle 

pub trait TaskResultHandle<R, E>: Send {
    // Required methods
    fn is_done(&self) -> bool;
    fn get(self) -> Result<R, TaskExecutionError<E>>
       where Self: Sized;
    fn try_get(self) -> TryGet<Self, R, E>
       where Self: Sized;
}

Common interface for handles that expose a submitted task’s final result.

Required Methods

fn is_done(&self) -> bool

Returns whether the task has installed a terminal state.

Returns

true after the task has reached a terminal lifecycle state. Result publication to the handle may still be racing with this observation.

fn get(self) -> Result<R, TaskExecutionError<E>>

where Self: Sized,

Blocks until the task produces its final result.

Returns

The final task result. If the completion endpoint is dropped without publishing a result, a dropped-result error is reported.

fn try_get(self) -> TryGet<Self, R, E>

where Self: Sized,

Attempts to retrieve the final result without blocking.

Returns

TryGet::Ready when a result is available, otherwise TryGet::Pending containing the original handle.
