Struct h2::server::Handshake

source · [−]

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

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.
