====== std.net.quic ======

QUIC (RFC 9000) ist ein modernes Transportprotokoll auf UDP-Basis, das von Google entwickelt und durch die IETF standardisiert wurde. Gegenüber TCP+TLS bietet QUIC integrierte TLS 1.3-Verschlüsselung, Stream-Multiplexing ohne Head-of-Line-Blocking und schnellere Verbindungsaufbauzeiten (0-RTT/1-RTT Handshake). QUIC ist die Transportschicht von HTTP/3.

Die Unit implementiert den QUIC-Handshake, Stream-Management (öffnen/schließen/lesen/schreiben), alle Frame-Typen (STREAM, ACK, PADDING, CRYPTO, CONNECTION_CLOSE) und variable-length Integer-Codierung (Varint). Einsatzbereiche sind hochperformante verschlüsselte Kommunikation und HTTP/3-Implementierungen.
