# nlohmann::adl_serializer
|
|
|
|
```
|
|
template<typename, typename>
|
|
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 similarly to
|
|
|
|
```
|
|
template<typename ValueType>
|
|
struct adl_serializer {
|
|
template<typename BasicJsonType>
|
|
static void to_json(BasicJsonType& j, const T& value) {
|
|
// calls the "to_json" method in T's namespace
|
|
}
|
|
|
|
template<typename BasicJsonType>
|
|
static void from_json(const BasicJsonType& j, T& value) {
|
|
// same thing, but with the "from_json" method
|
|
}
|
|
};
|
|
```
|
