C++ compile time function execution

Question

I have string tags in my code that are converted to numbers and used to search values in a tag-value structure.

I have something like this:

void foo(         


        

Answer 1

Althrough not compile time, I think this is fast enough for you;

void foo()
{
    const static auto someTagN = toNumber("SomeTag");
    type value = internal_search(someTagN );
}
