BSON_ITER_TYPE(3)

✨ BSON_ITER_TYPE ✨

okay bestie, so this is a libbson page, and honestly it's giving "short but iconic" 💅 like yes it's just one function but we're gonna learn it properly, no cap.

---

🌸 SYNOPSIS 🌸

so first things first, here's the whole bson_type_t enum in all its glory — every single value, exactly as it lives, don't come for me about the hex, it's all right here:

typedef enum {
   BSON_TYPE_EOD = 0x00,
   BSON_TYPE_DOUBLE = 0x01,
   BSON_TYPE_UTF8 = 0x02,
   BSON_TYPE_DOCUMENT = 0x03,
   BSON_TYPE_ARRAY = 0x04,
   BSON_TYPE_BINARY = 0x05,
   BSON_TYPE_UNDEFINED = 0x06,
   BSON_TYPE_OID = 0x07,
   BSON_TYPE_BOOL = 0x08,
   BSON_TYPE_DATE_TIME = 0x09,
   BSON_TYPE_NULL = 0x0A,
   BSON_TYPE_REGEX = 0x0B,
   BSON_TYPE_DBPOINTER = 0x0C,
   BSON_TYPE_CODE = 0x0D,
   BSON_TYPE_SYMBOL = 0x0E,
   BSON_TYPE_CODEWSCOPE = 0x0F,
   BSON_TYPE_INT32 = 0x10,
   BSON_TYPE_TIMESTAMP = 0x11,
   BSON_TYPE_INT64 = 0x12,
   BSON_TYPE_MAXKEY = 0x7F,
   BSON_TYPE_MINKEY = 0xFF,
} bson_type_t;

and then the actual star of the show, the function signature 🫶:

bson_type_t
bson_iter_type (const bson_iter_t *iter);
