Explicit type conversion between the JSON value and a compatible value which is not CopyConstructible and not DefaultConstructible. The value is converted by calling the json_serializer<ValueType> from_json() method.

The function is equivalent to executing

return JSONSerializer<ValueTypeCV>::from_json(*this);

This overloads is chosen if:

Note
If json_serializer<ValueType> has both overloads of from_json(), this one is chosen.
