+ * \defgroup CborEncoding Encoding to CBOR
+ * \brief Group of functions used to encode data to CBOR.
+ *
+ * CborEncoder is used to encode data into a CBOR stream. 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</h2>
+ *
+ * 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 illustrates expands on the one above and also
+ * deals with dynamically growing the buffer if the initial allocation wasn't
+ * big enough. Note the two places where the error checking was replaced with
+ * an assertion, showing where the author assumes no error can occur.
+ *
+ * \code
+ * uint8_t *encode_string_array(const char **strings, int n, size_t *bufsize)
+ * {
+ * CborError err;
+ * CborEncoder encoder, arrayEncoder;
+ * size_t size = 256;
+ * uint8_t *buf = NULL;
+ *
+ * while (1) {
+ * int i;
+ * size_t more_bytes;
+ * uint8_t *nbuf = realloc(buf, size);
+ * if (nbuf == NULL)
+ * goto error;
+ * buf = nbuf;
+ *
+ * cbor_encoder_init(&encoder, &buf, size, 0);
+ * err = cbor_encoder_create_array(&encoder, &arrayEncoder, n);
+ * assert(err); // can't fail, the buffer is always big enough
+ *
+ * for (i = 0; i < n; ++i) {
+ * err = cbor_encode_text_stringz(&arrayEncoder, strings[i]);
+ * if (err && err != CborErrorOutOfMemory)
+ * goto error;
+ * }
+ *
+ * err = cbor_encoder_close_container_checked(&encoder, &arrayEncoder);
+ * assert(err); // shouldn't fail!
+ *
+ * more_bytes = cbor_encoder_get_extra_bytes_needed(encoder);
+ * if (more_size) {
+ * // buffer wasn't big enough, try again
+ * size += more_bytes;
+ * continue;
+ * }
+ *
+ * *bufsize = cbor_encoder_get_buffer_size(encoder, buf);
+ * return buf;
