Storage of a `basic_json` value: the enumeration `value_t` holds the type, and the union `json_value` holds the value, as a pointer for objects, arrays, strings, and binary values and directly for booleans and numbers.
## Template arguments
The data types to store a JSON value are derived from the template arguments passed to class `basic_json`:
