WebJun 15, 2011 · As the result, MessagePack can serialize objects smaller than BSON. For example, a simple map {"a":1, "b":2} is serialized in 7 bytes with MessagePack, while BSON uses 19 bytes. BSON supports in-place updating. With BSON, you can modify part of stored object without re-serializing the whole of the object. WebThis is a standalone BSON ("binary JSON") library for C++. (See bsonspec.org for more information on the BSON format.) The library is at this time a bit early stage, but if you find it useful, that's great. Notes The code herein originates as a …

WebJan 5, 2016 · bsonspec.org lists a set of binary subtypes, including generic binary (\x00), function (\x01), UUID (\x04), MD5 (\x05), user defined (\x80). The questions are: What is the "function" subtype and what is it used for? If this is a compiled bytecode, are there any restrictions on it? Is it used in MongoDB? What user defined subtypes are there? WebYou can check this with the BSON_ITER_HOLDS_BINARY() macro or bson_iter_type(). The buffer that binary points to is only valid until the iterator's bson_t is modified or freed. Author how much water does clothes washer use
