HandshakePacket

This class models Quic Handshake Packets, as defined by RFC 9000, Section 17.2.4: 

A Handshake packet uses long headers with a type value of 0x02, followed
   by the Length and Packet Number fields; see Section 17.2. The first byte
   contains the Reserved and Packet Number Length bits; see Section 17.2.
   It is used to carry cryptographic handshake messages and acknowledgments
   from the server and client.

   Handshake Packet {
     Header Form (1) = 1,
     Fixed Bit (1) = 1,
     Long Packet Type (2) = 2,

   }
public interface
InitialPacket

This class models Quic Initial Packets, as defined by RFC 9000, Section 17.2.2:

   It carries the first CRYPTO frames sent by the client and server to perform
   key exchange, and it carries ACK frames in either direction.

     Header Form (1) = 1,
     Fixed Bit (1) = 1,
     Long Packet Type (2) = 0,
     Reserved Bits (2),         # Protected
     Packet Number Length (2),  # Protected
     Version (32),

     SCID Len (8),
     Source Connection ID (0..160),
     Token Length (i),
     Token (..),
     Length (i),
     Packet Number (8..32),     # Protected
     # Protected Packet Payload (..)
     Protected Payload (0..24), # Skipped Part
     Protected Payload (128),   # Sampled Part
     Protected Payload (..)     # Remainder
   }
public interface
LongHeaderPacket

This class models Quic Long Header Packets, as defined by RFC 8999, Section 5.1: 

Long Header Packet {
      Header Form (1) = 1,
      Version-Specific Bits (7),
      Version (32),
      Destination Connection ID Length (8),
      Destination Connection ID (0..2040),
      Source Connection ID Length (8),
      Source Connection ID (0..2040),
      Version-Specific Data (..),
   }
public interface
OneRttPacket

This class models Quic 1-RTT packets, as defined by RFC 9000, Section 17.3.1: 

A 1-RTT packet uses a short packet header. It is used after the
   version and 1-RTT keys are negotiated.

   1-RTT Packet {
     Header Form (1) = 0,
     Fixed Bit (1) = 1,
     Spin Bit (1),
     Reserved Bits (2),         # Protected
     Key Phase (1),             # Protected
     Packet Number Length (2),  # Protected
     Destination Connection ID (0..160),
     Packet Number (8..32),     # Protected
     # Protected Packet Payload:
     Protected Payload (0..24), # Skipped Part
     Protected Payload (128),   # Sampled Part
     Protected Payload (..),    # Remainder
   }
public interface
PacketSpace

An interface implemented by classes which keep track of packet numbers for a given packet number space.

public interface
QuicPacket

A super-interface for all specific Quic packet implementation classes.

public interface
RetryPacket

This class models Quic Retry Packets, as defined by RFC 9000, Section 17.2.5: 

A Retry packet uses a long packet header with a type value of 0x03.
   It carries an address validation token created by the server.
   It is used by a server that wishes to perform a retry; see Section 8.1.

   Retry Packet {
     Header Form (1) = 1,
     Fixed Bit (1) = 1,
     Long Packet Type (2) = 3,
     Unused (4),
     Version (32),
     Destination Connection ID Length (8),
     Destination Connection ID (0..160),
     Source Connection ID Length (8),
     Source Connection ID (0..160),
     Retry Token (..),
     Retry Integrity Tag (128),
   }
public interface
ShortHeaderPacket

This interface models Quic Short Header packets, as defined by RFC 8999, Section 5.2: 

Short Header Packet {
     Header Form (1) = 0,
     Version-Specific Bits (7),
     Destination Connection ID (..),
     Version-Specific Data (..),
   }
public interface
VersionNegotiationPacket

This class models Quic Version Negotiation Packets, as defined by RFC 9000, Section 17.2.1: 

A Version Negotiation packet is inherently not version-specific.
   Upon receipt by a client, it will be identified as a Version
   Negotiation packet based on the Version field having a value of 0.

   The Version Negotiation packet is a response to a client packet that
   contains a version that is not supported by the server, and is only
   sent by servers.

   The layout of a Version Negotiation packet is:

   Version Negotiation Packet {
     Header Form (1) = 1,
     Unused (7),
     Version (32) = 0,
     Destination Connection ID Length (8),
     Destination Connection ID (0..2040),
     Source Connection ID Length (8),
     Source Connection ID (0..2040),
     Supported Version (32) ...,
   }
public interface
ZeroRttPacket

This class models Quic 0-RTT Packets, as defined by RFC 9000, Section 17.2.3: 

A 0-RTT packet uses long headers with a type value of 0x01, followed
   by the Length and Packet Number fields; see Section 17.2. The first
   byte contains the Reserved and Packet Number Length bits; see Section 17.2.
   A 0-RTT packet is used to carry "early" data from the client to the server
   as part of the first flight, prior to handshake completion. As part of the
   TLS handshake, the server can accept or reject this early data.

   See Section 2.3 of [TLS13] for a discussion of 0-RTT data and its limitations.

   0-RTT Packet {
     Header Form (1) = 1,
     Fixed Bit (1) = 1,
     Long Packet Type (2) = 1,
     Reserved Bits (2),
     Packet Number Length (2),
     Version (32),
     Destination Connection ID Length (8),
     Destination Connection ID (0..160),
     Source Connection ID Length (8),
     Source Connection ID (0..160),
     Length (i),
     Packet Number (8..32),
     Packet Payload (..),
   }
