WebNew in version 2.8. bson. decode_iter (data, codec_options=CodecOptions (document_class=dict, tz_aware=False, uuid_representation=PYTHON_LEGACY)) ¶. Decode BSON data to multiple documents as a generator. Works similarly to the decode_all function, but yields one document at a time. WebBSON (Binary JSON) data. decode (as_class=, tz_aware=False, uuid_subtype=3, compile_re=True) ¶ Decode this BSON data. The default type to use for the resultant document is dict. Any other class that supports __setitem__ () can be used instead by passing it as the as_class parameter.

WebThe name "BSON" is based on the term JSON and stands for "Binary JSON". It is a binary form for representing simple or complex data structures including associative arrays (also known as name-value pairs), integer indexed arrays, and a suite of fundamental scalar types.

Webbson.decode_file_iter (file_obj, as_class=, tz_aware=True, uuid_subtype=3, compile_re=True, codec_options=None) ¶ Decode bson data from a file to multiple documents as a generator. Works similarly to the decode_all function, but reads from the file object in chunks and parses bson in chunks, yielding one document at a time. WebThe bson_t structure attempts to use an inline allocation within the structure to speed up performance of small documents. When this internal buffer has been exhausted, a heap allocated buffer will be dynamically allocated. Therefore, it is essential to call bson_destroy () on allocated documents. 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? secrets on the shore

Webbson_iter_binary (3) - This function shall return the binary data of a BSON_TYPE_BINARY element. It is a programming error to call this function on a field that is not of type BSON_TYPE_BINARY. You can check this with the BSON_ITER_HOLDS_BINARY() macro or bson_iter_type(). WebFor any pointer type, you need to keep the bsoncxx::document::value alive until you're done working with the data. Alternatively, you can copy the bytes out of the b_binary struct you get from get_binary and then let the document go. 0 2 Start watching this issue

WebThe BSON "binary" or "BinData" datatype is used to represent arrays of bytes. It is somewhat analogous to the Java notion of a ByteArray. BSON binary values have a subtype. This is used to indicate what kind of data is in the byte array. Subtypes from zero to 127 are predefined or reserved. Subtypes from 128-255 are user-defined.
