The class any describes a type-safe container for single values of any type.
1) An object of class
any stores an instance of any type that satisfies the constructor requirements or is empty, and this is referred to as the state of the class any object. The stored instance is called the contained object. Two states are equivalent if they are either both empty or if both are not empty and if the contained objects are equivalent.
2) The non-member
any_cast functions provide type-safe access to the contained object.
