Struct RpcCancel

Source 
struct RpcCancel {
    request_id: RequestId,
}
Expand description

Cancel a single request.

Note that calling this method does not guarantee that the request is actually cancelled: the request might finish first.

What we do guarantee is that either this method returns successfully and the request is cancelled, or that this method fails and the request is not cancelled. We also guarantee that both the request and this method will finish “fairly quickly” after this method is called.

In Arti’s current implementation, a cancel request is itself is not cancellable.

For more information see rpc-meta-draft.md.

Fields§

§request_id: RequestId

The ID for the request that we should try to cancel.
