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

[−] Expand description

Performs the HTTP/2.0 connection handshake.

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

The handshake is completed once both the connection preface and the initial settings frame is sent by the client.

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

See module level documentation for more details.

impl<T, B> Future for Handshake<T, B> where     T: AsyncRead + AsyncWrite,     B: IntoBuf,     B::Buf: 'static,

[+]

type Item = (SendRequest<B>, 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>,

[−]

[−]

Execute another future if this one resolves with an error.

fn select<B>(self, other: B) -> Select<Self, <B as IntoFuture>::Future> where     B: IntoFuture<Item = Self::Item, Error = Self::Error>,

[−]

Waits for either one of two futures to complete.
