Enum Handshake 

pub enum Handshake {
    None,
    AuthCommand,
    HelloMandatory,
}

Handshake style (PRO-001).

Variants

None

No RPC-layer handshake at all: the connection is usable immediately.

AuthCommand

HELLO optional; AUTH [api_key] / [user, pass] / [password]; pre-auth allowlist PING/HELLO/AUTH/QUIT.

Whether a deployment enforces credentials is its own config (ListenerConfig::auth_required), not a protocol dialect: a client with no credentials configured simply sends no AUTH, which is correct against an open deployment (PRO-001a).

HelloMandatory

HELLO must be the first frame, carrying credentials. The standard — see Config::standard.
