32 * \enum CborError
33 * \ingroup CborGlobals
34 * The CborError enum contains the possible error values used by the CBOR encoder and decoder.
35 *
36 * TinyCBOR functions report success by returning CborNoError, or one error
37 * condition by returning one of the values below. One exception is the
38 * out-of-memory condition (CborErrorOutOfMemory), which the functions for \ref
39 * CborEncoding may report in bit-wise OR with other conditions.
40 *
41 * This technique allows code to determine whether the only error condition was
42 * a lack of buffer space, which may not be a fatal condition if the buffer can
43 * be resized. Additionally, the functions for \ref CborEncoding may continue
44 * to be used even after CborErrorOutOfMemory is returned, and instead they
45 * will simply calculate the extra space needed.
46 *
47 * \value CborNoError No error occurred
48 * \omitvalue CborUnknownError
49 * \value CborErrorUnknownLength Request for the length of an array, map or string whose length is not provided in the CBOR stream
50 * \value CborErrorAdvancePastEOF Not enough data in the stream to decode item (decoding would advance past end of stream)
51 * \value CborErrorIO An I/O error occurred, probably due to an out-of-memory situation
52 * \value CborErrorGarbageAtEnd Bytes exist past the end of the CBOR stream
53 * \value CborErrorUnexpectedEOF End of stream reached unexpectedly
54 * \value CborErrorUnexpectedBreak A CBOR break byte was found where not expected
55 * \value CborErrorUnknownType An unknown type (future extension to CBOR) was found in the stream
56 * \value CborErrorIllegalType An invalid type was found while parsing a chunked CBOR string
57 * \value CborErrorIllegalNumber An illegal initial byte (encoding unspecified additional information) was found
58 * \value CborErrorIllegalSimpleType An illegal encoding of a CBOR Simple Type of value less than 32 was found
59 * \omitvalue CborErrorUnknownSimpleType
60 * \omitvalue CborErrorUnknownTag
61 * \omitvalue CborErrorInappropriateTagForType
62 * \omitvalue CborErrorDuplicateObjectKeys
63 * \value CborErrorInvalidUtf8TextString Illegal UTF-8 encoding found while parsing CBOR Text String
64 * \value CborErrorTooManyItems Too many items were added to CBOR map or array of pre-determined length
65 * \value CborErrorTooFewItems Too few items were added to CBOR map or array of pre-determined length
66 * \value CborErrorDataTooLarge Data item size exceeds TinyCBOR's implementation limits
67 * \value CborErrorNestingTooDeep Data item nesting exceeds TinyCBOR's implementation limits
68 * \omitvalue CborErrorUnsupportedType
69 * \value CborErrorJsonObjectKeyIsAggregate Conversion to JSON failed because the key in a map is a CBOR map or array
70 * \value CborErrorJsonObjectKeyNotString Conversion to JSON failed because the key in a map is not a text string
71 * \value CborErrorOutOfMemory During CBOR encoding, the buffer provided is insufficient for encoding the data item;
72 * in other situations, TinyCBOR failed to allocate memory
73 * \value CborErrorInternalError An internal error occurred in TinyCBOR
