make_indexes()

template<std::convertible_to< std::size_t > auto... vs>

auto kumi::make_indexes ( )

inlinenodiscardconstevalnoexcept

Creates a kumi::projection_map object, deducing the target type from the types of arguments.

Note

The arguments should model kumi::index

Template Parameters

vs	Zero or more values convertible to size_t to construct the indexes from.

Returns

A kumi::projection_map constructed from the vs

Examples:

#include <kumi/kumi.hpp>
#include <iostream>
 
using namespace kumi::literals;
 
int main()
{
  std::cout << kumi::projection_map{0_c, "a"_id} << "\n";
  std::cout << kumi::projection_map{0_c, 1_c, kumi::projection_map{2_c, 3_c}} << "\n\n"; 
 
  // Projections maps can be built from functions in simpler cases 
  std::cout << kumi::indexes(0_c, 1_c, 2_c) << "\n\n";
  std::cout << kumi::identifiers("a"_id, "b"_id) << "\n";
}
