none_of() [2/2]

template<typename Pred , typename Tuple >

KUMI_TRIVIAL_NODISCARD constexpr bool kumi::none_of ( Tuple const &  ts, Pred  p  )

constexprnoexcept

Checks if unary predicate p returns true for no elements in the value t.

Parameters

ts	Value to process.
p	Unary predicate.

Returns

The evaluation of !any_of(ts,p).

Example:

 
#include <kumi/tuple.hpp>
#include <iostream>
 
int main()
{
  auto t = kumi::tuple{1,2.,3.f};
  std::cout << std::boolalpha << kumi::none_of( t, [](auto e) { return e > 10.; }) << "\n";
  std::cout << std::boolalpha << kumi::none_of( 8, [](auto e) { return e > 10.; }) << "\n";
 
  auto u = kumi::tuple{0,0.,0.f};
  std::cout << std::boolalpha << kumi::none_of( u ) << "\n";
}
