Usage

Wrapping a Future<T> to Future<Result<T, E>>

final result = Future((){...}).toResultOrError<Exception>();

Mapping a Future<Result<T, E>> to Future<Result<U, E>>

return getDataResult().next(
    onSuccess: (T success) {
        ...
        return Success(processed_value);
    },
    onError: (E error) async {
        ...
        if (is_recoverable_error){
            ...
            return Success(recupered_error);
        }
        ...
        return Error(propagated_error);
    },
