# [Detailed Description](#Detailed_Description)

## [template<class T>](#template_class_T_)

struct cereal::BinaryData< T >"A wrapper around data that can be serialized in a binary fashion.

This class is used to demarcate data that can safely be serialized as a binary chunk of data. Individual archives can then choose how best represent this during serialization.

## [template<class T> using **cereal::BinaryData**< T >::PT](#template_class_T__using_)

**Initial value:**

```
typename std::conditional<std::is_const<typename std::remove_pointer<typename std::remove_reference<T>::type>::type>::value,


                                        const void *,


                                        void *>::type
```

```

```

Internally store the pointer as a void \*, keeping const if created with a const pointer
