Package-Level Constants (total 25, all are exported)

const DefaultAckDelayExponent = 3 DefaultAckDelayExponent is the default ack delay exponent

const DefaultActiveConnectionIDLimit = 2 DefaultActiveConnectionIDLimit is the default active connection ID limit

const DefaultMaxAckDelay time.Duration = 25000000 DefaultMaxAckDelay is the default max_ack_delay

const ECNCE ECN = 4 // 11

const ECNNon ECN = 1 // 00

const ECNUnsupported ECN = 0

const ECT0 ECN = 3 // 10

const ECT1 ECN = 2 // 01

const InvalidByteCount ByteCount = -1 InvalidByteCount is an invalid byte count

const InvalidPacketLimitAES = 4503599627370496 InvalidPacketLimitAES is the maximum number of packets that we can fail to decrypt when using AEAD_AES_128_GCM or AEAD_AES_265_GCM.

const InvalidPacketLimitChaCha = 68719476736 InvalidPacketLimitChaCha is the maximum number of packets that we can fail to decrypt when using AEAD_CHACHA20_POLY1305.

const MaxAckDelayExponent = 20 MaxAckDelayExponent is the maximum ack delay exponent

const MaxByteCount ByteCount = 4611686018427387903 MaxByteCount is the maximum value of a ByteCount

const MaxConnIDLen = 20 MaxConnIDLen is the maximum length of the connection ID

const MaxLargePacketBufferSize = 20480 MaxLargePacketBufferSize is used when using GSO

const MaxMaxAckDelay time.Duration = 16383000000 MaxMaxAckDelay is the maximum max_ack_delay

const MaxPacketBufferSize = 1452 MaxPacketBufferSize maximum packet size of any QUIC packet, based on ethernet's max size, minus the IP and UDP headers. IPv6 has a 40 byte header, UDP adds an additional 8 bytes. This is a total overhead of 48 bytes. Ethernet's max packet size is 1500 bytes, 1500 - 48 = 1452.

const MinConnectionIDLenInitial = 8 MinConnectionIDLenInitial is the minimum length of the destination connection ID on an Initial packet.

const MinInitialPacketSize = 1200 MinInitialPacketSize is the minimum size an Initial packet is required to have.

const MinStatelessResetSize = 42 // token MinStatelessResetSize is the minimum size of a stateless reset packet that we send

const MinUnknownVersionPacketSize = 1200 MinUnknownVersionPacketSize is the minimum size a packet with an unknown version needs to have in order to trigger a Version Negotiation packet.

const PacketType0RTT PacketType = 4 PacketType0RTT is the packet type of a 0-RTT packet

const PacketTypeHandshake PacketType = 3 PacketTypeHandshake is the packet type of a Handshake packet

const PacketTypeInitial PacketType = 1 PacketTypeInitial is the packet type of an Initial packet

const PacketTypeRetry PacketType = 2 PacketTypeRetry is the packet type of a Retry packet
