__init__(*, alpha: Alpha, beta: Beta, gamma: Gamma, delta: Delta, eta: Eta, iota: Iota, kappa: Kappa, lambda_: Lambda_ = None, rho: Rho, tau: U32, phi: Phi, chi: Chi, psi: Psi, pi: Pi, theta: Theta, xi: Xi) → 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.
