std::sub_match::length(3)

💅 std::sub_match::length(3) — C++ Standard Libary manual realness ✨

okay so bestie, welcome to the std::sub_match::length page from the C++ Standard Libary manual 🦋 this one is short, sweet, and lowkey iconic — no cap.

✨ NAME ✨

std::sub_match::length — and yes, the description is literally also std::sub_match::length 💅 it’s giving “the name is the name, periodt.”

🎀 Synopsis 🎀

difference_type length() const;

that’s the whole signature, bestie — clean, const, and ready to slay 🔥

🌸 Parameters 🌸

• (none) — literally no parameters, not a single one, we love a no-argument moment 🫶

💖 Return value 💖

Returns the number of characters in the match, i.e. std::distance(first, second) if the match is valid, 0 otherwise. fr fr, that’s the whole vibe check: valid match gets the character count, invalid match gets 0 💀

⭐ Complexity ⭐

Constant. yup — constant time, no drama, main character energy only 👑
