max_flat()

template<concepts::product_type T, typename F>

auto kumi::max_flat ( T && t, F f )

inlinenodiscardconstexprnoexcept

Computes the maximum value of applications of f to all elements of kumi::flatten_all(t).

Parameters

t	Tuple to inspect
f	Unary Callable object

Returns

The maximum value of f over all elements of a flattened version of t

Helper type

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

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

Examples:

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

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