Struct script::fetch::FetchCanceller

pub struct FetchCanceller {
    cancel_chan: Option<IpcSender<()>>,
}

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

cancel_chan: Option<IpcSender<()>>
