BSON_ITER_OVERWRITE_DECIMAL128(3)

💅 BSON_ITER_OVERWRITE_DECIMAL128(3) 💅

ok so bestie, welcome to the libbson girlies 🎀 — this one's all about bson_iter_overwrite_decimal128, and yes it's a mouthful, but it's literally so iconic once you get it.

---

✨ SYNOPSIS ✨

bool
bson_iter_overwrite_decimal128 (bson_iter_t *iter, const bson_decimal128_t *value);

---

🌸 PARAMETERS 🌸

• iter — a bson_iter_t. you know her, you love her, she's the iterator doing the observing 👀
• value — the new Decimal128 value. the fresh new content, the glow-up in question 💖

---

🦋 DESCRIPTION 🦋

okay so, bson_iter_overwrite_decimal128() shall overwrite the contents of a BSON_TYPE_DECIMAL128 element in place. in place, bestie — no copy, no moving, just straight-up swapping the contents right where they live. slay.

🫶 but hear me out: this may only be done when the underlying bson document allows mutation. if it doesn't, that's not a vibe and definitely not allowed.

and then the serious one 😭 — it is a programming error to call this function when iter is not observing an element of type BSON_TYPE_DECIMAL128. like, that's on you, not on libbson. vibe check your types before you call, fr fr 💀
