The outermost + * CborEncoder is initialized by calling cbor_encoder_init(), with the buffer + * where the CBOR stream will be stored. The outermost CborEncoder is usually + * used to encode exactly one item, most often an array or map. It is possible + * to encode more than one item, but care must then be taken on the decoder + * side to ensure the state is reset after each item was decoded. + * + * Nested CborEncoder objects are created using cbor_encoder_create_array() and + * cbor_encoder_create_map(), later closed with cbor_encoder_close_container() + * or cbor_encoder_close_container_checked(). The pairs of creation and closing + * must be exactly matched and their parameters are always the same. + * + * CborEncoder writes directly to the user-supplied buffer, without extra + * buffering. CborEncoder does not allocate memory and CborEncoder objects are + * usually created on the stack of the encoding functions. + * + * The example below initializes a CborEncoder object with a buffer and encodes + * a single integer. + * + * \code + * uint8_t buf[16]; + * CborEncoder encoder; + * cbor_encoder_init(&encoder, &buf, sizeof(buf), 0); + * cbor_encode_int(&encoder, some_value); + * \endcode + * + * As explained before, usually the outermost CborEncoder object is used to add + * one array or map, which in turn contains multiple elements. The example + * below creates a CBOR map with one element: a key "foo" and a boolean value. + * + * \code + * uint8_t buf[16]; + * CborEncoder encoder, mapEncoder; + * cbor_encoder_init(&encoder, &buf, sizeof(buf), 0); + * cbor_encoder_create_map(&encoder, &mapEncoder, 1); + * cbor_encode_text_stringz(&mapEncoder, "foo"); + * cbor_encode_boolean(&mapEncoder, some_value); + * cbor_encoder_close_container(&encoder, &mapEncoder); + * \endcode + * + * <h3 class="groupheader">Error checking and buffer size</h3> + * + * All functions operating on CborEncoder return a condition of type CborError. + * If the encoding was successful, they return CborNoError. Some functions do + * extra checking on the input provided and may return some other error + * conditions (for example, cbor_encode_simple_value() checks that the type is + * of the correct type). + * + * In addition, all functions check whether the buffer has enough bytes to + * encode the item being appended. If that is not possible, they return + * CborErrorOutOfMemory. + * + * It is possible to continue with the encoding of data past the first function + * that returns CborErrorOutOfMemory. CborEncoder functions will not overrun + * the buffer, but will instead count how many more bytes are needed to + * complete the encoding. At the end, you can obtain that count by calling + * cbor_encoder_get_extra_bytes_needed(). + * + * \section1 Finalizing the encoding + * + * Once all items have been appended and the containers have all been properly + * closed, the user-supplied buffer will contain the CBOR stream and may be + * immediately used. To obtain the size of the buffer, call + * cbor_encoder_get_buffer_size() with the original buffer pointer. + * + * The example below illustrates how one can encode an item with error checking + * and then pass on the buffer for network sending. + * + * \code + * uint8_t buf[16]; + * CborError err; + * CborEncoder encoder, mapEncoder; + * cbor_encoder_init(&encoder, &buf, sizeof(buf), 0); + * err = cbor_encoder_create_map(&encoder, &mapEncoder, 1); + * if (!err) + * return err; + * err = cbor_encode_text_stringz(&mapEncoder, "foo"); + * if (!err) + * return err; + * err = cbor_encode_boolean(&mapEncoder, some_value); + * if (!err) + * return err; + * err = cbor_encoder_close_container_checked(&encoder, &mapEncoder); + * if (!err) + * return err; + * + * size_t len = cbor_encoder_get_buffer_size(&encoder, buf); + * send_payload(buf, len); + * return CborNoError; + * \endcode + * + * Finally, the example below expands on the one above and also + * deals with dynamically growing the buffer if the initial allocation wasn't + * big enough.

The main data type for the parsing is a CborValue, which behaves + * like an iterator and can be used to extract the encoded data. It is first + * initialized with a call to cbor_parser_init() and is usually used to extract + * exactly one item, most often an array or map. + * + * Nested CborValue objects can be parsed using cbor_value_enter_container(). + * Each call to cbor_value_enter_container() must be matched by a call to + * cbor_value_leave_container(), with the exact same parameters. + * + * The example below initializes a CborParser object, begins the parsing with a + * CborValue and decodes a single integer: + * + * \code + * int extract_int(const uint8_t *buffer, size_t len) + * { + * CborParser parser; + * CborValue value; + * int result; + * cbor_parser_init(buffer, len, 0, &parser, &value); + * cbor_value_get_int(&value, &result); + * return result; + * } + * \endcode + * + * The code above does no error checking, which means it assumes the data comes + * from a source trusted to send one properly-encoded integer. The following + * example does the exact same operation, but includes error checking and + * returns 0 on parsing failure: + * + * \code + * int extract_int(const uint8_t *buffer, size_t len) + * { + * CborParser parser; + * CborValue value; + * int result; + * if (cbor_parser_init(buffer, len, 0, &parser, &value) != CborNoError) + * return 0; + * if (!cbor_value_is_integer(&value) || + * cbor_value_get_int(&value, &result) != CborNoError) + * return 0; + * return result; + * } + * \endcode + * + * Note, in the example above, that one can't distinguish a parsing failure + * from an encoded value of zero. Reporting a parsing error is left as an + * exercise to the reader. + * + * The code above does not execute a range-check either: it is possible that + * the value decoded from the CBOR stream encodes a number larger than what can + * be represented in a variable of type \c{int}. If detecting that case is + * important, the code should call cbor_value_get_int_checked() instead. + * + * <h3 class="groupheader">Memory and parsing constraints</h3> + * + * TinyCBOR is designed to run with little memory and with minimal overhead. + * Except where otherwise noted, the parser functions always run on constant + * time (O(1)), do not recurse and never allocate memory (thus, stack usage is + * bounded and is O(1)). + * + * <h3 class="groupheader">Error handling and preconditions</h3> + * + * All functions operating on a CborValue return a CborError condition, with + * CborNoError standing for the normal situation in which no parsing error + * occurred. All functions may return parsing errors in case the stream cannot + * be decoded properly, be it due to corrupted data or due to reaching the end + * of the input buffer. + * + * Error conditions must not be ignored. All decoder functions have undefined + * behavior if called after an error has been reported, and may crash. + * + * Some functions are also documented to have preconditions, like + * cbor_value_get_int() requiring that the input be an integral value. + * Violation of preconditions also results in undefined behavior and the + * program may crash. + */ + +/** + * \addtogroup CborParsing + * @{ + */ + +/** + * \struct CborValue + * + * This type contains one value parsed from the CBOR stream.
