CborMajorType

class cometa.cbor.cbor_major_type.CborMajorType(value)

Bases: IntEnum

Represents CBOR Major Types as defined in RFC 7049 section 2.1.

These major types are used to identify the type of data in a CBOR data item.

UNSIGNED_INTEGER = 0

An unsigned integer. Range: 0 to 2^64-1 inclusive. The value of the encoded item is the argument itself.

NEGATIVE_INTEGER = 1

A negative integer. Range: -2^64 to -1 inclusive. The value of the item is -1 minus the argument.

BYTE_STRING = 2

A byte string. The number of bytes in the string is equal to the argument.

UTF8_STRING = 3

A text string encoded as UTF-8. Refer to Section 2 and RFC 3629. The number of bytes in the string is equal to the argument.

ARRAY = 4

An array of data items. The argument specifies the number of data items in the array.

MAP = 5

A map of pairs of data items.

TAG = 6

A tagged data item (“tag”). Tag number ranges from 0 to 2^64-1 inclusive. The enclosed data item (tag content) follows the head.

SIMPLE = 7

Simple values, floating-point numbers, and the “break” stop code.

UNDEFINED = 4294967295

Undefined major type.

to_string()

Returns a human-readable string representation of this CBOR major type.

Returns:

A string representation of the major type.

Return type:

str

Example

>>> from cometa.cbor import CborMajorType
>>> major_type = CborMajorType.UNSIGNED_INTEGER
>>> major_type.to_string()
'Unsigned Integer'
