MONGOC_COLLECTION_CREATE_INDEX(3)

💖 MONGOC_COLLECTION_CREATE_INDEX 💖

okay bestie, so this one is a libmongoc page — yes, the C driver for MongoDB, we're in the trenches today 🫶 — and the function is mongoc_collection_create_index. It does exactly what it says on the tin: it makes an index on a collection. Cute, right? Well... keep reading, because there's a vibe check coming. 😭

🚨 WARNING 🚨

Deprecated since version 1.8.0. Not me showing up to tell you this thing is basically a fossil 💀 — the official word is: see Manage Collection Indexes for alternatives.

So like, it still exists, it's still here, but it's giving "exhibit in a museum" energy. If you're writing new code, go look at the alternatives instead. No cap. 🙈

✨ SYNOPSIS ✨

bool
mongoc_collection_create_index (mongoc_collection_t *collection,
                                const bson_t *keys,
                                const mongoc_index_opt_t *opt,
                                bson_error_t *error);

Look at that return type — a bool. So it comes back and tells you yes or no, slay. ✅

🎀 PARAMETERS 🎀

• collection — a mongoc_collection_t. This is the collection you're about to make iconic with an index. Your main character, literally. 👑
• keys — a bson_t. This is the blueprint of the index — the keys and the direction and all that jazz, all wrapped up in BSON. 💅
• opt — a mongoc_index_opt_t. The options struct, aka the little outfit your index wears. ✨
• error — an optional spot to drop a bson_error_t if things go sideways, or NULL if you're feeling brave and don't want the tea. 😭
