💅 BSON_ITER_KEY_LEN(3)

okay so bestie, welcome to libbson's little corner of the manual, this one's called BSON_ITER_KEY_LEN and it is honestly so underrated. tiny function, huge time-save, let's get into it ✨

✨ SYNOPSIS ✨

uint32_t
bson_iter_key_len (const bson_iter_t *iter);

that's it. that's the whole vibe check. 🫶

🎀 PARAMETERS 🎀

  • iter — a bson_iter_t. yeah. that one. the iterator you're already holding, no cap.

🌸 DESCRIPTION 🌸

so what does it do? it fetches the length of the key for the current element that iter is observing. that's the whole thing. that's the assignment. 💖

and here's the iconic part — this is a constant time computation. so it's literally faster than calling strlen() on a key you got back from bson_iter_key(). like, why would you do the slow thing when the fast thing exists?? not me judging, just saying 👀

the way that this is just free performance sitting right there. obsessed. 🔥

⭐ RETURNS ⭐

an integer representing the key length. slay. that's your answer. 🎀

💌 SEE ALSO

  • bson_iter_key() — to retrieve the current key. like, the key itself, not just its length. different function, different job, both iconic. 👑
