pub(super) struct InProgressClientRequest {
pub request: Request,
pub tx: MustUseClientResponseSender,
pub span: Span,
}
Expand description
A message from the peer::Client
to the peer::Server
,
after it has been received by the peer::Server
.
Fields§
§request: Request
The actual request.
tx: MustUseClientResponseSender
The return message channel, included because peer::Client::call
returns a
future that may be moved around before it resolves.
INVARIANT: tx.send()
must be called before dropping tx
.
JUSTIFICATION: the peer::Client
translates Request
s into
ClientRequest
s, which it sends to a background task. If the send is
Ok(())
, it will assume that it is safe to unconditionally poll the
Receiver
tied to the Sender
used to create the ClientRequest
.
We also take advantage of this invariant to route inventory requests away from peers that did not respond with that inventory.
We enforce this invariant via the type system, by converting
ClientRequest
s to InProgressClientRequest
s when they are received by
the background task. These conversions are implemented by
ClientRequestReceiver
.
span: Span
The tracing context for the request, so that work the connection task does processing messages in the context of this request will have correct context.
