Detailed Description

template<class R, class F, class... Args>
struct Dune::Std::is_invocable_r< R, F, Args >

Traits class to check if function is invocable and the return type is compatible.

Template Parameters

R	Desired result type
F	Function to check
Args	Function arguments to check

This checks if F can be called with an arguments list of type Args..., and if the return value can be converted to R. The result is encoded by deriving from std::ingegral_constant<bool, result>.

This implements std::is_invocable_r from C++17.
