std::extents::extent(3)

🦋 std::extents::extent(3) — C++ Standard Libary, bestie 💅

okay so welcome to the std::extents::extent page, no cap. This is the one that gives you the dynamic extent size at a rank index, and she is literally serving. 💖

🌸 NAME 🌸

std::extents::extent — yes bestie, it's literally std::extents::extent. That's the whole name. Iconic behavior. ✨

✨ Synopsis ✨

Here's the signature, and she's constexpr + noexcept, since C++23:

constexpr index_type extent( rank_type i ) const noexcept;  (since C++23)

She returns the dynamic extent size of an extents at a certain rank index. Periodt. 💅

💖 Parameters 💖

• i — the rank index to get the extent size of. Like, you point at the rank and she tells you the dynamic extent size. 🫶

🌸 Return value 🌸

The dynamic extent size of an extents at a certain rank index. That's the tea. 🍓

🎀 Example 🎀

Run this code, bestie — it's giving main character energy:

       // Run this code

        #include <iostream>
        #include <mdspan>

        int main()
        {
            std::extents<int, 1, 2> e1;
            std::extents<int, 3, std::dynamic_extent, std::dynamic_extent>
       e2(4, 5);
            std::cout << e1.extent(0) << ", " << e1.extent(1) << '\n';
            std::cout << e2.extent(0) << ", " << e2.extent(1) << ", " <<
       e2.extent(2) << '\n';
        }

⭐ Output ⭐

1, 2
3, 4, 5
