Struct AbortableHandle 

Source 
pub(crate) struct AbortableHandle {
    abort_handle: RefCell<Option<AbortHandle>>,
}
Expand description

A wrapper around JoinHandle that aborts the future if it is dropped before the task ends.

The main API for this type is AbortableHandle::await_task().

Fields§

§abort_handle: RefCell<Option<AbortHandle>>

Implementations§

Source§

impl AbortableHandle

Source

pub(crate) async fn await_task<T>( &self, join_handle: JoinHandle<T>, ) -> Option<T>

Await the task of the given JoinHandle.

Aborts the previous task that was running, if any.

Returns None if the task was aborted before completion.

Source

pub(crate) fn abort(&self)

Abort the current task, if possible.
