Available on crate feature async only.

Extension methods for JoinHandle and AbortOnDropHandle.

Required Methods

fn wait_and_assert_finished<'async_trait>( self ) -> Pin<Box<dyn Future<Output = T> + Send + 'async_trait>>

where Self: 'async_trait,

Waits for the task to finish, resuming the unwind if the task panicked.

Because this takes ownership of self, and JoinHandle and AbortOnDropHandle don’t offer abort methods, this can avoid worrying about aborted tasks.

fn abort_and_wait<'async_trait>( self ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: 'async_trait,

Aborts the task, then waits for it to complete.
