# adl_serializer ```cpp template struct adl_serializer; ``` Serializer that uses ADL ([Argument-Dependent Lookup](https://en.cppreference.com/w/cpp/language/adl)) to choose `to_json`/`from_json` functions from the types' namespaces. It is implemented similar to ```cpp template struct adl_serializer { template static void to_json(BasicJsonType& j, const T& value) { // calls the "to_json" method in T's namespace } template static void from_json(const BasicJsonType& j, T& value) { // same thing, but with the "from_json" method } }; ``` ## Member functions - **from_json** - convert a JSON value to any value type - **to_json** - convert any value type to a JSON value
