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).
- Returns a byte vector containing the BSON serialization.
- Writes the BSON serialization to an output adapter.
Parameters
j
(in)- JSON value to serialize
o
(in)- output adapter to write serialization to
Return value
- BSON serialization as byte vector
- /
Exception safety
Strong guarantee: if an exception is thrown, there are no changes in the JSON value.
Complexity
Linear in the size of the JSON value j
.
Example
??? 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"
```
