func Close(client *mongo.Client, ctx context.Context,
	cancel context.CancelFunc)

This is a method to close resources. This method closes mongoDB connection and cancel context.

func Connect

func Connect(uri string) (*mongo.Client, context.Context, context.CancelFunc, error)

This is a method that returns mongo.Client, context.Context, context.CancelFunc and error.

func DeleteMany

func DeleteMany(client *mongo.Client, ctx context.Context,
	dataBase, col string, query interface{}) (result *mongo.DeleteResult, err error)

deleteMany is a user defined function that deletes multiple documents from the collection.

func DeleteOne

func DeleteOne(client *mongo.Client, ctx context.Context,
	dataBase, col string, query interface{}) (result *mongo.DeleteResult, err error)

deleteOne is a user defined function that deletes a single document from the collection.

func FindOne

func FindOne(client *mongo.Client, ctx context.Context, dataBase, col string, query, field interface{}) (result *mongo.SingleResult)

find a single element matching a query

func InsertMany

func InsertMany(client *mongo.Client, ctx context.Context, dataBase, col string, docs []interface{}) (*mongo.InsertManyResult, error)

	dataBase, col string, query, field interface{}) (result *mongo.Cursor, err error)

query method returns a cursor and error.

func UpdateOne

func UpdateOne(client *mongo.Client, ctx context.Context, dataBase,
	col string, filter, update interface{}) (result *mongo.UpdateResult, err error)
