Struct FetchCanceller

pub(crate) struct FetchCanceller {
    request_id: Option<RequestId>,
}

RAII fetch canceller object. By default initialized to not having a canceller in it, however you can ask it for a cancellation receiver to send to Fetch in which case it will store the sender. You can manually cancel it or let it cancel on Drop in that case.

Fields

request_id: Option<RequestId>
