cbor_indefinite_len_array

Module for CBOR decoding/encoding indefinite length arrays. Indefinite length arrays are encoded without writing the array length, so elements shall be read until the termination byte is found.

NOTE: encoding of values greater than 2^64 is not supported.

class CborIds(value)

Bases: IntEnum

Enumerative for CBOR identifiers.

UINT8 = 24

UINT16 = 25

UINT32 = 26

UINT64 = 27

INDEF_LEN_ARRAY_START = 159

INDEF_LEN_ARRAY_END = 255

class CborIndefiniteLenArrayConst

Bases: object

Class container for CBOR indefinite length arrays constants.

UINT_IDS_TO_BYTE_LEN: Dict[int, int] = {CborIds.UINT8: 2, CborIds.UINT16: 3, CborIds.UINT32: 5, CborIds.UINT64: 9}

class CborIndefiniteLenArrayDecoder

Bases: object

CBOR indefinite length arrays decoder. It decodes bytes back to array.

static Decode(enc_bytes: bytes) → List[int]

CBOR-decode the specified bytes.

Parameters:: enc_bytes (bytes) – Encoded bytes
Returns:: List of integers
Return type:: list[int]
Raises:: ValueError – If encoding is not valid

class CborIndefiniteLenArrayEncoder

Bases: object

CBOR indefinite length arrays encoder. It encodes indefinite length arrays to bytes.

static Encode(int_seq: Sequence[int]) → bytes

CBOR-encode the specified elements.

Parameters:: int_seq (sequence[int]) – Collection of integers
Returns:: CBOR-encoded bytes
Return type:: bytes
