all_of() [1/2]

template<typename T >

constexpr auto kumi::all_of ( T const &  ts )

constexprnoexcept

Computes the reduction of a tuple over the && operator.

Parameters

ts	Value to process.

Returns

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

Example:

 
#include <kumi/tuple.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";
  std::cout << std::boolalpha << kumi::all_of( -3.3, [](auto e) { return e < 5; }) << "\n";
 
  auto u = kumi::tuple{true,false,true,false};
  std::cout << std::boolalpha << kumi::all_of(u) << "\n";
}
