Struct catalyzer::internals::crates::tokio::task::AbortHandle

pub struct AbortHandle { /* private fields */ }

An owned permission to abort a spawned task, without awaiting its completion.

Unlike a JoinHandle, an AbortHandle does not represent the permission to await the task’s completion, only to terminate it.

The task may be aborted by calling the AbortHandle::abort method. Dropping an AbortHandle releases the permission to terminate the task — it does not abort the task.

Implementations

impl AbortHandle

pub fn abort(&self)

Abort the task associated with the handle.

Awaiting a cancelled task might complete as usual if the task was already completed at the time it was cancelled, but most likely it will fail with a cancelled JoinError.

If the task was already cancelled, such as by JoinHandle::abort, this method will do nothing.

See also the module level docs for more information on cancellation.

pub fn is_finished(&self) -> bool

Checks if the task associated with this AbortHandle has finished.

Please note that this method can return false even if abort has been called on the task. This is because the cancellation process may take some time, and this method does not return true until it has completed.
