Detailed Description

template<typename T, typename... Args>
struct amrex::IsCallable< T, Args >

Test if a given type T is callable with arguments of type Args...

This type trait is different from std::is_invocable since it only cares for the call syntax f(args...) and disregards pointers to class methods and such.

For consistency we use IsCallable over is_invocable since AMReX relies on call syntax everywhere else. Using an equivalent function to std::invoke would increase call stacks in debug mode, add more template instantiations and will obfuscate lots of generic code that takes functions.
