# basic_json::to_bson
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
// (1)
|
||
|
|
static std::vector<std::uint8_t> to_bson(const basic_json& j);
|
||
|
|
|
||
|
|
// (2)
|
||
|
|
static void to_bson(const basic_json& j, detail::output_adapter<std::uint8_t> o);
|
||
|
|
static void to_bson(const basic_json& j, detail::output_adapter<char> o);
|
||
|
|
```
|
||
|
|
|
||
|
|
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).
|
||
|
|
|
||
|
|
1. Returns a byte vector containing the BSON serialization.
|
||
|
|
2. 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
|
||
|
|
|
||
|
|
1. BSON serialization as byte vector
|
||
|
|
2. /
|
||
|
|
|
||
|
|
## 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"
|
||
|
|
```
