[−][src]Struct futures_util::task::JoinHandle
#[must_use = "futures do nothing unless polled"]pub struct JoinHandle<T> { /* fields omitted */ }
The join handle returned by
spawn_with_handle.
Methods
impl<T> JoinHandle<T>[src]
impl<T> JoinHandle<T>pub fn forget(self)[src]
pub fn forget(self)Drops this handle without canceling the underlying future.
This method can be used if you want to drop the handle, but let the execution continue.
