__init__(num_blocks: Int, num_tickets: Int, num_preimages: Int, num_octets: Int, num_reports: Int, num_avail: Int) → None

Initialize the Codable.

Parameters:

  • codec – Optional codec to use for encoding/decoding

  • enc_sequence – Optional function that returns sequence of fields to encode

static decode_from(buffer: bytes | bytearray | memoryview, offset: int = 0) → Tuple[T, int]

Decode from buffer. Must be implemented by subclasses or added via decorator.

Parameters:

  • buffer – Buffer to decode from

  • offset – Starting position in buffer

Returns:

  • The decoded value

  • Number of bytes read

Return type:

Tuple containing

encode_into(buffer: bytearray, offset: int = 0) → int

Encode into provided buffer.

encode_size() → int

Calculate number of bytes needed to encode.
