Struct cros_async::sys::linux::fd_executor::PendingOperation

source · 
pub struct PendingOperation {
    token: Option<WakerToken>,
    ex: Weak<RawExecutor<EpollReactor>>,
}
Expand description

A token returned from add_operation that can be used to cancel the waker before it completes. Used to manage getting the result from the underlying executor for a completed operation. Dropping a PendingOperation will get the result from the executor.
