Implementations

impl<T> JoinError<T>

pub fn is_canceled(&self) -> bool

Returns true if a task failed to join because it was canceled.

pub fn is_completed(&self) -> bool

Returns true if the task completed successfully before it was canceled.

pub fn id(&self) -> TaskId

Returns the TaskId of the task that failed to join.

pub fn output(self) -> Option<T>

Returns the task’s output, if the task completed successfully before it was canceled.

Otherwise, returns None.

fn eq(&self, other: &JoinError<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
