max() [2/2]

template<concepts::product_type T, typename F>

auto kumi::max ( T && t, F f )

inlinenodiscardconstexprnoexcept

Computes the maximum value of applications of f to all elements of t.

Parameters

t	Tuple to inspect
f	Unary Callable object

Returns

The maximum value of f over all elements of t

Helper type

namespace kumi
{
  template<typename T, typename F> struct max;
 
  template<typename T, typename F>
  using max_t = typename max<T, F>::type;
}

Computes the type returned by a call to kumi::max.

Examples:

#include <kumi/kumi.hpp>
#include <iostream>
 
int main()
{
  auto f0 = kumi::tuple {1, 'A', 99.77f, 3. };
  auto f1 = kumi::tuple {2., f0, 3.f };
 
  std::cout << kumi::max(f0) << "\n";
  std::cout << kumi::max(f1, [](auto m) { return sizeof(m); }) << "\n";
}

#include <kumi/kumi.hpp>
#include <iostream>
 
int main()
{
  using namespace kumi::literals;
  auto f0 = kumi::record {"a"_id = 1, "b"_id = 'A', "c"_id = 99.77f, "d"_id = 3. };
  auto f1 = kumi::record {"a"_id = 2., "b"_id = f0, "c"_id = 3.f };
 
  std::cout << kumi::max(f0) << "\n";
  std::cout << kumi::max(f1, [](auto m) { return sizeof(m); }) << "\n";
}
