SYNOPSIS
char *
mongoc_collection_keys_to_index_string (const bson_t *keys);
PARAMETERS
- keys
- A bson_t \&.
DESCRIPTION
This function shall returns the canonical stringification, as used in mongoc_collection_create_index(3) without an explicit name, of a given key specification.
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.
