# adl_serializer
```cpp
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 similar to
```cpp
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
}
};
```
## Member functions
- **from_json** - convert a JSON value to any value type
- **to_json** - convert any value type to a JSON value

# basic_json::get_to
```cpp
template<typename ValueType>
ValueType& get_to(ValueType& v) const noexcept(
noexcept(JSONSerializer<ValueType>::from_json(
std::declval<const basic_json_t&>(), v)))
```
Explicit type conversion between the JSON value and a compatible value. The value is filled into the input parameter by
calling the `json_serializer<ValueType>` `from_json()` method.
The function is equivalent to executing
```cpp
ValueType v;
JSONSerializer<ValueType>::from_json(*this, v);
```
This overloads is chosen if:
- `ValueType` is not `basic_json`,
- `json_serializer<ValueType>` has a `from_json()` method of the form `void from_json(const basic_json&, ValueType&)`
## Template parameters
`ValueType`
: the value type to return
## Return value
the input parameter, allowing chaining calls
## Exceptions
Depends on what `json_serializer<ValueType>` `from_json()` method throws
## Example
??? example
The example below shows several conversions from JSON values to other types. There a few things to note: (1)
Floating-point numbers can be converted to integers, (2) A JSON array can be converted to a standard
`#!cpp std::vector<short>`, (3) A JSON object can be converted to C++ associative containers such as
`#cpp std::unordered_map<std::string, json>`.
```cpp
--8<-- "examples/get_to.cpp"
```
Output:
```json
--8<-- "examples/get_to.output"
```
## Version history
- Since version 3.3.0.

using json_serializer = JSONSerializer<T, SFINAE>;
```
## Template parameters
`T`
: type to convert; will be used in the `to_json`/`from_json` functions

: type to add compile type checks via SFINAE; usually `#!cpp void`
## Notes
#### Default type
The default values for `json_serializer` is [`adl_serializer`](../adl_serializer.md).
## Version history
- Since version 2.0.0.
