Hey hey,
figuring out the syntax for c++20 concepts I run into challenges. With a two
parameter template concept like swappable_with or convertible_to is it always
necessary to use a requires statement like this:
template<typename T>
requires std::convertible_to<T,int>
void f(T t) ...
...
With single parameter concepts like integral a syntax like this will work:
template<std::integral T>
void f(T t)...
Also with single parameter concepts a statement like this should work:
std::integral auto my_variable;
Will that work with a two parameter concept like the above convertible_to? I
haven't seen/found a syntax which does it.
Any help is appreciated, definitely including a good read that WILL
demonstrate or demystify these things.
Best wishes,
Jeanette
