So brauchen Sie vorher nicht zu wissen, wie die Feld-/Attributnamen lauten (wie es bei Pydantic-Modellen der Fall wäre).

Das ist nützlich, wenn Sie Schlüssel empfangen, deren Namen Sie nicht bereits kennen.

---

Ein anderer nützlicher Anwendungsfall ist, wenn Sie Schlüssel eines anderen Typs haben wollen, z. B. `int`.

	tcpTimeForFirstByteTotalDur uint64
}{}

// RPCStats holds information about the DHCP/TCP metrics and errors
type RPCStats struct {
	Errs uint64

	DialAvgDuration uint64
	TTFBAvgDuration uint64
	DialErrs        uint64
}

// GetRPCStats returns RPC stats, include calls errors and dhcp/tcp metrics
func GetRPCStats() RPCStats {
	s := RPCStats{
		Errs:     atomic.LoadUint64(&globalStats.errs),

 * Don't start a new attempt until 250 ms after the most recent attempt was started.
 * Keep whichever TCP connection succeeds first and cancel all the others.
 * Race TCP only. Only attempt a TLS handshake on the winning TCP connection.

After this, the client and the server have an **encrypted TCP connection**, this is what TLS provides. And then they can use that connection to start the actual **HTTP communication**.

And that's what **HTTPS** is, it's just plain **HTTP** inside a **secure TLS connection** instead of a pure (unencrypted) TCP connection.
