BSON (Binary JSON) is a binary format in which zero or more ordered key/value pairs are stored as a single entity (a so-called document).
j
(in) : JSON value to serialize
o
(in) : output adapter to write serialization to
Strong guarantee: if an exception is thrown, there are no changes in the JSON value.
Linear in the size of the JSON value j
.
??? example
The example shows the serialization of a JSON value to a byte vector in BSON format. ```cpp --8<-- "examples/to_bson.cpp" ``` Output: ```json --8<-- "examples/to_bson.output" ```
