Is it possible to have a class template accept either of one (unsigned int, typename) parameter, based upon what was given?
Example of what I mean:
template<??>
class Bytes
{
// ....
};
Bytes<4> FourBytes;
Bytes<int> FourBytes;
Bytes<DWORD64> EightBytes;
Iam aware of the template<auto T>, though was thinking if there was a different solution?
Template parameters need to either be a type, or a value, there isn't a placeholder for something that can be either a type or a value. That said, you can make a couple factory functions to help you. That could look like
template<std::size_t N>
class Bytes
{
// ....
};
template <typename T>
auto make_bytes() { return Bytes<sizeof(T)>{}; }
template <std::size_t N>
auto make_bytes() { return Bytes<N>{}; }
and you would declare objects like
auto FourBytesValue = make_bytes<4>();
auto FourBytesType = make_bytes<int>();
auto EightBytes = make_bytes<DWORD64>();
