Why is initDBService defined even though it is not used in the function?

Line 62 in 28eea61

func (initDBService *InitDBService) createDatabase(dsn string, driver string, createSql string) error {

Is there a Go-specific writing style?

The part "(initDBService * InitDBService)" meant that you specified a structure that could access this function.
