Result<V extends Object, E extends Exception> class
sealed
成功もしくは失敗の可能性があることを示す型.
V で void を指定したい場合, 代わりに Complete を指定する.
Constructors
-
Result.fromResult(Result<
V, E> result, Type? classLocation, String? functionLocation, Map<String, dynamic> monitor, Map<String, dynamic> debug, Iterable<Log> histories) -
syntax sugar.
factory
-
Result.wrapException(E wrapExceptionFactory(Exception exception), Result<
V, Exception> result, Type? classLocation, String? functionLocation, Map<String, dynamic> monitor, Map<String, dynamic> debug, Iterable<Log> histories) -
syntax sugar.
