Struct h2::RecvStream [−][src]
pub struct RecvStream { /* fields omitted */ }
Expand description
Receives the body stream and trailers from the remote peer.
A RecvStream
is provided by client::ResponseFuture
and
server::Connection
with the received HTTP/2 message head (the response
and request head respectively).
A RecvStream
instance is used to receive the streaming message body and
any trailers from the remote peer. It is also used to manage inbound flow
control.
See method level documentation for more details on receiving data. See
FlowControl
for more details on inbound flow control.
Implementations
Get optional trailers for this stream.
Poll for the next data frame.
Returns true if the receive half has reached the end of stream.
A return value of true
means that calls to poll
and poll_trailers
will both return None
.
Get a mutable reference to this stream’s FlowControl
.
It can be used immediately, or cloned to be used later.
Trait Implementations
Attempt to pull out the next value of this stream, registering the
current task for wakeup if the value is not yet available, and returning
None
if the stream is exhausted. Read more
