Struct hyper::client::dispatch::Sender

pub(crate) struct Sender<T, U> {
    buffered_once: bool,
    giver: Giver,
    inner: UnboundedSender<Envelope<T, U>>,
}

A bounded sender of requests and callbacks for when responses are ready.

While the inner sender is unbounded, the Giver is used to determine if the Receiver is ready for another request.

Fields

buffered_once: bool

One message is always allowed, even if the Receiver hasn’t asked for it yet. This boolean keeps track of whether we’ve sent one without notice.

giver: Giver

The Giver helps watch that the the Receiver side has been polled when the queue is empty. This helps us know when a request and response have been fully processed, and a connection is ready for more.

inner: UnboundedSender<Envelope<T, U>>

Actually bounded by the Giver, plus buffered_once.
