Struct h2::server::Handshake

    builder: Builder,
    state: Handshaking<T, B>,
    span: Span,
}
Expand description

In progress HTTP/2 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.

Fields§

§builder: Builder

The config to pass to Connection::new after handshake succeeds.

§state: Handshaking<T, B>

The current state of the handshake.

§span: Span

Span tracking the handshake
