```
template<class To, class From>
constexpr To bit_cast(const From& from) noexcept;
```

Implicitly creates objects nested within the result ([intro.object]).

Each bit of the value representation of the result
is equal to the corresponding bit in the object representation
of from.

Padding bits of the result are unspecified.

For the result and each object created within it,
if there is no value of the object's type corresponding to the
value representation produced, the behavior is undefined.

If there are multiple such values, which value is produced is unspecified.

Remarks: This function is constexpr if and only if
To, From, and the types of all subobjects
of To and From are types T such that:

- is_union_v<T> is false;
- is_pointer_v<T> is false;
- is_member_pointer_v<T> is false;
- is_volatile_v<T> is false; and
- T has no non-static data members of reference type.
