SYNOPSIS

typedef struct _mongoc_index_model_t mongoc_index_model_t;
mongoc_index_model_t *
mongoc_index_model_new (const bson_t *keys, const bson_t *opts);
void mongoc_index_model_destroy (mongoc_index_model_t *model);
bool
mongoc_collection_create_indexes_with_opts (mongoc_collection_t *collection,


                                            mongoc_index_model_t **models,


                                            size_t n_models,


                                            const bson_t *opts,


                                            bson_t *reply,


                                            bson_error_t *error);


PARAMETERS


opts may be NULL or a BSON document with additional command options:

  • writeConcern: Construct a mongoc_write_concern_t <> and use mongoc_write_concern_append() <> to add the write concern to opts. See the example code for mongoc_client_write_command_with_opts() <>.
  • sessionId: First, construct a mongoc_client_session_t <> with mongoc_client_start_session() <>. You can begin a transaction with mongoc_client_session_start_transaction() <>, optionally with a mongoc_transaction_opt_t <> that overrides the options inherited from collection, and use mongoc_client_session_append() <> to add the session to opts. See the example code for mongoc_client_session_t <>.
  • collation: Configure textual comparisons. See Setting Collation Order <https://www.mongodb.com/docs/languages/c/c-driver/current/libmongoc/guides/bulk/#setting-collation-order>, and the MongoDB Manual entry on Collation <https://www.mongodb.com/docs/manual/reference/collation/>. Collation requires MongoDB 3.2 or later, otherwise an error is returned.
  • serverId: To target a specific server, include an int32 "serverId" field. Obtain the id by calling mongoc_client_select_server() <>, then mongoc_server_description_id() <> on its return value.

Additional options passed in opts are appended to the createIndexes command. See the MongoDB Manual for createIndexes <https://www.mongodb.com/docs/manual/reference/command/createIndexes/> for all supported options.

If no write concern is provided in opts, the collection's write concern is used.

mongoc_index_model_t

Each mongoc_index_model_t represents an index to create. mongoc_index_model_new includes:
