template<typename Pred , product_type T>

constexpr auto kumi::all_of ( T &&  ts, Pred  p  )

inlineconstexprnoexcept

Checks if unary predicate p returns true for all elements in the value t.

Parameters

ts	Value to process.
p	Unary predicate.

Returns

The evaluation of p(get<0>(ts)) && ... && p(get<N-1>(ts)) where N is the size of ts.

Example:

 
#include <kumi/kumi.hpp>
#include <iostream>
 
int main()
{
  auto t = kumi::tuple{1,2.,3.f};
  std::cout << std::boolalpha << kumi::all_of( t, [](auto e) { return e < 5; }) << "\n";
 
  auto u = kumi::tuple{true,false,true,false};
  std::cout << std::boolalpha << kumi::all_of(u) << "\n";
}
