pub struct Connection<T, B: IntoBuf = Bytes> { /* fields omitted */ }
Manages all state associated with an HTTP/2.0 client connection.
A Connection
is backed by an I/O resource (usually a TCP socket) and
implements the HTTP/2.0 client logic for that connection. It is responsible
for driving the internal state forward, performing the work requested of the
associated handles (SendRequest
, ResponseFuture
, SendStream
,
RecvStream
).
Connection
values are created by calling handshake
. Once a
Connection
value is obtained, the caller must repeatedly call poll
until Ready
is returned. The easiest way to do this is to submit the
Connection
instance to an executor.
client::handshake(my_io)
.and_then(|(send_request, connection)| {
my_executor.execute(
connection.map_err(|_| panic!("connection failed"))
).unwrap();
})
Sets the target window size for the whole connection.
If size
is greater than the current value, then a WINDOW_UPDATE
frame will be immediately sent to the remote, increasing the connection
level window by size - current_value
.
If size
is less than the current value, nothing will happen
immediately. However, as window capacity is released by
ReleaseCapacity
instances, no WINDOW_UPDATE
frames will be sent
out until the number of "in flight" bytes drops below size
.
The default value is 65,535.
See ReleaseCapacity
documentation for more details.
