Description: ## AWS S3 Construct Library
        
        Define an unencrypted S3 bucket.
        
        ```ts
        new Bucket(this, 'MyFirstBucket');
        ```
        
        `Bucket` constructs expose the following deploy-time attributes:
        
         * `bucketArn` - the ARN of the bucket (i.e. `arn:aws:s3:::bucket_name`)
         * `bucketName` - the name of the bucket (i.e. `bucket_name`)
         * `bucketUrl` - the URL of the bucket (i.e.
           `https://s3.us-west-1.amazonaws.com/onlybucket`)
         * `arnForObjects(...pattern)` - the ARN of an object or objects within the
           bucket (i.e.
           `arn:aws:s3:::my_corporate_bucket/exampleobject.png` or
           `arn:aws:s3:::my_corporate_bucket/Development/*`)
         * `urlForObject(key)` - the URL of an object within the bucket (i.e.
           `https://s3.cn-north-1.amazonaws.com.cn/china-bucket/mykey`)
        
        ### Encryption
        
        Define a KMS-encrypted bucket:
        
        ```ts
        const bucket = new Bucket(this, 'MyUnencryptedBucket', {
            encryption: BucketEncryption.Kms
        });
        
        // you can access the encryption key:
        assert(bucket.encryptionKey instanceof kms.EncryptionKey);
        ```
        
        You can also supply your own key:
        
        ```ts
        const myKmsKey = new kms.EncryptionKey(this, 'MyKey');
        
        const bucket = new Bucket(this, 'MyEncryptedBucket', {
            encryption: BucketEncryption.Kms,
            encryptionKey: myKmsKey
        });
        
        assert(bucket.encryptionKey === myKmsKey);
        ```
        
        Use `BucketEncryption.ManagedKms` to use the S3 master KMS key:
        
        ```ts
        const bucket = new Bucket(this, 'Buck', {
            encryption: BucketEncryption.ManagedKms
        });
        
        assert(bucket.encryptionKey == null);
        ```
        
        ### Permissions
        
        A bucket policy will be automatically created for the bucket upon the first call to
        `addToResourcePolicy(statement)`:
        
        ```ts
        const bucket = new Bucket(this, 'MyBucket');
        bucket.addToResourcePolicy(new iam.PolicyStatement()
          .addActions('s3:GetObject')
          .addResources(bucket.arnForObjects('file.txt'))
          .addAccountRootPrincipal());
        ```
        
        Most of the time, you won't have to manipulate the bucket policy directly.
        Instead, buckets have "grant" methods called to give prepackaged sets of permissions
        to other resources. For example:
        
        ```ts
        const lambda = new lambda.Function(this, 'Lambda', { /* ... */ });
        
        const bucket = new Bucket(this, 'MyBucket');
        bucket.grantReadWrite(lambda.role);
        ```
        
        Will give the Lambda's execution role permissions to read and write
        from the bucket.
        
        ### Sharing buckets between stacks
        
        To use a bucket in a different stack in the same CDK application, pass the object to the other stack:
        
        ```ts
        
        /**
         * Stack that defines the bucket
         */
        class Producer extends cdk.Stack {
            public readonly myBucket: s3.Bucket;
        
            constructor(scope: cdk.App, id: string, props?: cdk.StackProps) {
                super(scope, id, props);
        
                const bucket = new s3.Bucket(this, 'MyBucket', {
                  removalPolicy: cdk.RemovalPolicy.Destroy
                });
                this.myBucket = bucket;
            }
        }
        
        interface ConsumerProps extends cdk.StackProps {
            userBucket: s3.IBucket;
        }
        
        /**
         * Stack that consumes the bucket
         */
        class Consumer extends cdk.Stack {
            constructor(scope: cdk.App, id: string, props: ConsumerProps) {
                super(scope, id, props);
        
                const user = new iam.User(this, 'MyUser');
                props.userBucket.grantReadWrite(user);
            }
        }
        
        const producer = new Producer(app, 'ProducerStack');
        new Consumer(app, 'ConsumerStack', { userBucket: producer.myBucket });
        ```
        
        ### Importing existing buckets
        
        To import an existing bucket into your CDK application, use the `Bucket.import` factory method.  This method accepts a
        `BucketImportProps` which describes the properties of the already existing bucket:
        
        ```ts
        const bucket = Bucket.import(this, {
            bucketArn: 'arn:aws:s3:::my-bucket'
        });
        
        // now you can just call methods on the bucket
        bucket.grantReadWrite(user);
        ```
        
        ### Bucket Notifications
        
        The Amazon S3 notification feature enables you to receive notifications when
        certain events happen in your bucket as described under [S3 Bucket
        Notifications] of the S3 Developer Guide.
        
        To subscribe for bucket notifications, use the `bucket.onEvent` method. The
        `bucket.onObjectCreated` and `bucket.onObjectRemoved` can also be used for these
        common use cases.
        
        The following example will subscribe an SNS topic to be notified of all
        ``s3:ObjectCreated:*` events:
        
        ```ts
        const myTopic = new sns.Topic(this, 'MyTopic');
        bucket.onEvent(s3.EventType.ObjectCreated, myTopic);
        ```
        
        This call will also ensure that the topic policy can accept notifications for
        this specific bucket.
        
        The following destinations are currently supported:
        
         * `sns.Topic`
         * `sqs.Queue`
         * `lambda.Function`
        
        It is also possible to specify S3 object key filters when subscribing. The
        following example will notify `myQueue` when objects prefixed with `foo/` and
        have the `.jpg` suffix are removed from the bucket.
        
        ```ts
        bucket.onEvent(s3.EventType.ObjectRemoved, myQueue, { prefix: 'foo/', suffix: '.jpg' });
        ```

        ### Block Public Access
        
        Use `blockPublicAccess` to specify [block public access settings] on the bucket.
        
        Enable all block public access settings:
        ```ts
        const bucket = new Bucket(this, 'MyBlockedBucket', {
            blockPublicAccess: BlockPublicAccess.BlockAll
        });
        ```
        
        Block and ignore public ACLs:
        ```ts
        const bucket = new Bucket(this, 'MyBlockedBucket', {
            blockPublicAccess: BlockPublicAccess.BlockAcls
        });
        ```
        
        Alternatively, specify the settings manually:
        ```ts
        const bucket = new Bucket(this, 'MyBlockedBucket', {
            blockPublicAccess: new BlockPublicAccess({ blockPublicPolicy: true })
        });
        ```
        
        When `blockPublicPolicy` is set to `true`, `grantPublicRead()` throws an error.
