          char *
          mongoc_collection_keys_to_index_string (const bson_t *keys);

PARAMETERS

       • keys: A bson_t. This is expected to match the form of the key field in the createIndexes command.

DESCRIPTION

       This  function  returns the canonical stringification of a given key specification. See Manage Collection
       Indexes for example usage.

       It is a programming error to call this function on a non-standard index, such one other than  a  straight
       index with ascending and descending.

RETURNS

       A string that should be freed with bson_free().
