Trait a10::cancel::Cancel

pub trait Cancel {
    // Required methods
    fn try_cancel(&mut self) -> CancelResult;
    fn cancel(&mut self) -> CancelOp<'_> ;
}

Cancelation of an in progress operations.

Required Methods

fn try_cancel(&mut self) -> CancelResult

Attempt to cancel this operation.

The cancelation attempt will be done asynchronously, without returning the result. If you want to know the result of the cancelation attempt use cancel instead.

fn cancel(&mut self) -> CancelOp<'_>

Cancel this operation.

If this returns ENOENT it means the operation was not found. This can be caused by the operation never starting, due to the inert nature of Futures, or the operation has already been completed.

If this returns EALREADY it means the operation was found, but it was already canceled previously.

If the operation was found and canceled this returns Ok(()).

If this is called on an AsyncIterator it will cause them to return None (eventually, it may still return pending items).
