QpackInteger class

QPACK integer encoder/decoder per RFC 9204 Section 4.1.

QPACK reuses the HPACK integer representation from RFC 7541. An integer is encoded into the lower prefixBits of the first byte; the remaining upper bits of that byte are reserved for the enclosing instruction and are left as zero by these helpers. Callers must OR in the instruction bits before transmission.

prefixBits = 1..8 prefixLimit = 2^prefixBits - 1 If value < prefixLimit: encode in one byte. Else: first byte = prefixLimit, then encode remainder with 7-bit continuation (MSB = 1 for more bytes, 0 for last).

Static Methods

decode(Uint8List bytes, int offset, int prefixBits) → (int, int)

encode(int value, int prefixBits) → Uint8List

Encode value using a prefixBits-bit prefix (1..8).
