Trait tokio_tower::multiplex::client::TagStore[−][src]

pub trait TagStore<Request, Response> {
    type Tag: Eq;
    fn assign_tag(self: Pin<&mut Self>, r: &mut Request) -> Self::Tag;

    fn finish_tag(self: Pin<&mut Self>, r: &Response) -> Self::Tag;
}
Expand description

A transport capable of transporting tagged requests and responses must implement this interface in order to be used with a Client.

Note that we require self to be pinned here as assign_tag and finish_tag are called on the transport, which is already pinned so that we can use it as a Stream + Sink. It wouldn’t be safe to then give out &mut to the transport without Pin, as that might move the transport.
