template<arithmetic_scalar_value Type, typename Cardinal >

template<eve::invocable< size_type > Generator>

eve::wide< Type, Cardinal >::wide ( Generator &&  g )

inlinenoexcept

The Callable Object must satisfy the following prototype:

T generator(std::ptrdiff_t index);

and is supposed to return the value computed from the current index to store at said index.

Parameters

g	The Callable Object to use as a value generator

Example:

#include <eve/wide.hpp>
#include <iostream>
 
int main()
{
  // Generates the wide [0 2 4 ... ]
  eve::wide<int> r = [](auto i) { return i * 2; };
  std::cout << r << "\n";
}
