Enum TlsAlpnPreference 

pub enum TlsAlpnPreference {
    Auto,
    Http1Only,
}

Per-call hint for how a TLS connector should advertise ALPN.

Auto leaves protocol selection to the connector’s default behavior. Http1Only is used by WebSocket-over-TLS calls, which must complete an HTTP/1.1 upgrade handshake and therefore must not negotiate HTTP/2.
