This is a malloc-free implementation of the Concise Binary Object Representation (CBOR) data format for the RIOT-OS. This implementation mostly stand-alone, and it should be pretty easy to port to other platforms. We're only using the C STL and some custom network-related functionaliy which could be easily replaced by depending on arpa/inet.h. The CBOR API is straight-forward to use and provides encoding/decoding functionality for all major C types, such as: - int - uint64_t - int64_t - float - double - char* - struct tm - time_t It is possible to conditionally compile this module via CFLAGS: - CBOR_NO_SEMANTIC_TAGGING: All semantic-tagging features removed - CBOR_NO_CTIME: All ctime related features removed - CBOR_NO_FLOAT: All floating-point related features removed - CBOR_NO_PRINT: All features depending on printf removeddev/timer

* @brief Implementation of a CBOR serializer/deserializer in C |
||||
* |
||||
* @author Kevin Funk <kfunk@kde.org> |
||||
* @author Jana Cavojska <jana.cavojska9@gmail.com> |
||||
* |
||||
* This is an implementation suited for constrained devices |
||||
* Characteristics: |
||||
* - No dynamic memory allocation (i.e. no calls to @e malloc, @e free) used throughout the implementation |
||||
* - User may allocate static buffers, this implementation uses the space provided by them (cf. @ref cbor_stream_t) |
||||
* |
||||
* @par Supported types (categorized by major type (MT)): |
||||
* |
||||
* - Major type 0 (unsigned integer): Full support. Relevant functions: |
||||
* - cbor_serialize_int(), cbor_deserialize_int() |
||||
* - cbor_serialize_uint64_t(), cbor_deserialize_uint64_t() |
||||
* |
||||
* - Major type 1 (negative integer): Full support. Relevant functions: |
||||
* - cbor_serialize_int(), cbor_deserialize_int() |
||||
* - cbor_serialize_int64_t(), cbor_deserialize_int64_t() |
||||
* |
||||
* - Major type 2 (byte string): Full support. Relevant functions: |
||||
* - cbor_serialize_byte_string(), cbor_deserialize_byte_string() |
||||
* |
||||
* - Major type 3 (unicode string): Basic support (see below). Relevant functions: |
||||
* - cbor_serialize_unicode_string(), cbor_deserialize_unicode_string() |
||||
* |
||||
* - Major type 4 (array of data items): Full support. Relevant functions: |
||||
* - cbor_serialize_array(), cbor_deserialize_array() |
||||
* - cbor_serialize_indefinite_array(), cbor_deserialize_indefinite_array(), cbor_at_break() |
||||
* |
||||
* - Major type 5 (map of pairs of data items): Full support. Relevant functions: |
||||
* - cbor_serialize_map(), cbor_deserialize_map() |
||||
* - cbor_serialize_indefinite_map(), cbor_deserialize_indefinite_map(), cbor_at_break() |
||||
* |
||||
* - Major type 6 (optional semantic tagging of other major types): Basic support (see below). Relevant functions: |
||||
* - cbor_write_tag() |
||||
* - cbor_deserialize_date_time() |
||||
* - cbor_serialize_date_time() |
||||
* |
||||
* - Major type 7 (floating-point numbers and values with no content): Basic support (see below). Relevant functions: |
||||
* - cbor_serialize_float_half(), cbor_deserialize_float_half() |
||||
* - cbor_serialize_float(), cbor_deserialize_float() |
||||
* - cbor_serialize_double(), cbor_deserialize_double() |
||||
* - cbor_serialize_bool(), cbor_deserialize_bool() |
||||
* |
||||
* @par Notes about major type 3: |
||||
* Since we do not have a standardised C type for representing Unicode code points, |
||||
* we just provide API to serialize/deserialize @e char* arrays. The user then |
||||
* has to transform that into a meaningful representation |
||||
* |
||||
* @par Notes about major type 6 (cf. https://tools.ietf.org/html/rfc7049#section-2.4):
|
||||
* Encoding date and time: date/time strings that follow the standard format described in Section 3.3 of [RFC3339]: |
||||
* 2003-12-13T18:30:02Z - supported |
||||
* 2003-12-13T18:30:02.25Z - not supported |
||||
* 2003-12-13T18:30:02+01:00 - not supported |
||||
* 2003-12-13T18:30:02.25+01:00 - not supported |
||||
* Since we do not have C types for representing bignums/bigfloats/decimal-fraction |
||||
* we do not provide API to serialize/deserialize them at all. |
||||
* You can still read out the actual data item behind the tag (via cbor_deserialize_byte_string()) |
||||
* and interpret it yourself. |
||||
* |
||||
* @par Notes about major type 7 and simple values (cf. https://tools.ietf.org/html/rfc7049#section-2.3)
|
||||
* Simple values: |
||||
* - 0-19: (Unassigned) - No support |
||||
* - 20,21: True, False - Supported (see cbor_serialize_bool(), cbor_deserialize_bool()) |
||||
* - 22,23: Null, Undefined - No support (what's the use-case?) |
||||
* - 24-31: (Reserved) - No support |
||||
* - 32-255: (Unassigned) - No support |
||||
* |
||||
* TODO: API for Indefinite-Length Byte Strings and Text Strings |
||||
* (see https://tools.ietf.org/html/rfc7049#section-2.2.2)
