a JSON value
The actual storage for a JSON value of the basic_json class. This union combines the different storage types for the JSON value types defined in value_t.
- Note
- Variable-length types (objects, arrays, and strings) are stored as pointers. The size of the union should not exceed 64 bits if the default value types are used.
- Since
- version 1.0.0
