Struct multistream_select::Negotiated
source · pub struct Negotiated<TInner> { /* private fields */ }Expand description
An I/O stream that has settled on an (application-layer) protocol to use.
A Negotiated represents an I/O stream that has settled on a protocol
to use. In particular, it is not implied that all of the protocol negotiation
frames have yet been sent and / or received, just that the selected protocol
is fully determined. This is to allow the last protocol negotiation frames
sent by a peer to be combined in a single write, possibly piggy-backing
data from the negotiated protocol on top.
Reading from a Negotiated I/O stream that still has pending negotiation
protocol data to send implicitly triggers flushing of all yet unsent data.
