pub struct Handshake<T, B: IntoBuf = Bytes> { /* fields omitted */ }

[−] Expand description

In progress HTTP/2.0 connection handshake future.

This type implements Future, yielding a Connection instance once the handshake has completed.

The handshake is completed once the connection preface is fully received from the client and the initial settings frame is sent to the client.

The handshake future does not wait for the initial settings frame from the client.

See module level docs for more details.

[+]

type Item = Connection<T, B>

type Error = Error

The type of error that this future will resolve with if it fails in a normal fashion.

fn poll(&mut self) -> Poll<Self::Item, Self::Error>

[−]

Query this future to see if its value has become available, registering interest if it is not.

fn wait(self) -> Result<Self::Item, Self::Error>

[−]

Map this future's error to a different error, returning a new future.

fn from_err<E>(self) -> FromErr<Self, E> where     E: From<Self::Error>,

[−]
