CborArray

Encode a class as a CBOR Array (Major type 4) instead of a CBOR map.

Serialization of such a class will skip element names (or labels), only encoding the values (containing explicit nulls where necessary).

Example usage:

@CborArray
@Serializable
data class DataClass(
    val alg: Int,
    val kid: String?
)

Cbor.encodeToByteArray(DataClass(alg = -7, kid = null))

will produce bytes 0x8226F6, or in diagnostic notation:

82    # array(2)
   26 # negative(6)
   F6 # primitive(22)

This may be used to encode COSE structures, see RFC 9052 2. Basic COSE Structure.
