bson_iter_key_len - bson_iter_key_len()
uint32_t bson_iter_key_len (const bson_iter_t *iter);
Fetches the length of the key for the current element observed by iter. This is a constant time computation, and therefore faster than calling strlen() on a key returned by bson_iter_key().
An integer representing the key length.
