template <typename E, auto Begin = kDefaultEnumValueBegin, auto End = kDefaultEnumValueEnd, auto... Ints>
```
```
size_t CountEnumElement ()
```
Count number of elements in an enum / enum class type |E|.

This compile-time function checks all the values in sequence {Begin,

Begin + 1, ..., End - 1} to count all defined enum values at compilation

time.

template <typename E, auto Begin = kDefaultEnumValueBegin, auto End = kDefaultEnumValueEnd, auto... Ints>
```
```
std::optional<decltype(Begin)> MaxEnumElementValue ()
```
Get the maximum element in an enum / enum class type |E|.

This compile-time function checks all the values in sequence {Begin,

Begin + 1, ..., End - 1} to find the maximum defined enum values at

compilation time.

```
```
std::optional<decltype(Begin)> MinEnumElementValue ()
```
Get the minimum element in an enum / enum class type |E|.

This compile-time function checks all the values in sequence {Begin,

Begin + 1, ..., End - 1} to find the minimum defined enum values at

compilation time.
