std::mdspan::size(3)

okay bestie, welcome to the std::mdspan::size(3) page — manual name? C++ Standard Libary (yes, that spelling, not me 👀). This one is short, but it's still giving main character energy.

🌸 NAME 🌸

std::mdspan::size — literally std::mdspan::size, that's the whole name bestie. Iconic.

🦋 Synopsis 🦋

constexpr size_type size() const noexcept;  (since C++23)

Returns the number of elements in mdspan.

It's equivalent to extents().fwd-prod-of-extents(rank()).

🚨 okay so listen: if the size of the multidimensional index space extents() is not representable as a value of type size_type, the behavior of the program is undefined. Like, no cap, that's UB — stay safe out there. 💀

🌈 Parameters 🌈

• (none) — yep, zero parameters. nada. zilch. we love a low-maintenance icon. ✨

🎀 Return value 🎀

The number of elements. that's it. that's the whole vibe. 💖
