Detailed Description

template<typename R, typename FUNC, typename... TN>
class bsl::is_invocable_r< R, FUNC, TN >

If the provided args form a callable, and is convertible to "R", provides the member constant value equal to true. Otherwise the member constant value is false.

#include <bsl/is_invocable_r.hpp>
#include <bsl/debug.hpp>

namespace bsl
{
    inline void
    example_is_invocable_r_overview() noexcept
    {
        if (bsl::is_invocable_r<bool(), bool()>::value) {
            bsl::print() << "success\n";
        }
    }
}

Template Parameters

R	the type that "FUNC" should be convertible to
FUNC	the type that defines the function being called
TN	the types that define the arguments passed to the provided function when called.
