template <typename BasicJsonType> std::string to_string(const BasicJsonType& j);
This function implements a user-defined to_string for JSON objects.
BasicJsonType
: a specialization of basic_json
string containing the serialization of the JSON value
Strong guarantee: if an exception is thrown, there are no changes to any JSON value.

if a string stored inside the JSON value is not UTF-8 encoded
Linear.

??? example
The following code shows how the library's `to_string()` function integrates with others, allowing argument-dependent lookup. ```cpp --8<-- "examples/to_string.cpp" ``` Output: ```json --8<-- "examples/to_string.output" ```
