Struct aws_sdk_s3::operation::list_objects_v2::builders::ListObjectsV2FluentBuilder

pub struct ListObjectsV2FluentBuilder { /* private fields */ }

Fluent builder constructing a request to ListObjectsV2.

Returns some or all (up to 1,000) of the objects in a bucket with each request. You can use the request parameters as selection criteria to return a subset of the objects in a bucket. A 200 OK response can contain valid or invalid XML. Make sure to design your application to parse the contents of the response and handle it appropriately. For more information about listing objects, see Listing object keys programmatically in the Amazon S3 User Guide. To get a list of your buckets, see ListBuckets.

Directory buckets - For directory buckets, you must make requests for this API operation to the Zonal endpoint. These endpoints support virtual-hosted-style requests in the format https://bucket_name.s3express-az_id.region.amazonaws.com/key-name . Path-style requests are not supported. For more information, see Regional and Zonal endpoints in the Amazon S3 User Guide.

Permissions

• General purpose bucket permissions - To use this operation, you must have READ access to the bucket. You must have permission to perform the s3:ListBucket action. The bucket owner has this permission by default and can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources in the Amazon S3 User Guide.

• Directory bucket permissions - To grant access to this API operation on a directory bucket, we recommend that you use the CreateSession API operation for session-based authorization. Specifically, you grant the s3express:CreateSession permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the CreateSession API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another CreateSession API call to generate a new session token for use. Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, see CreateSession .

Sorting order of returned objects

• General purpose bucket - For general purpose buckets, ListObjectsV2 returns objects in lexicographical order based on their key names.

• Directory bucket - For directory buckets, ListObjectsV2 does not return objects in lexicographical order.

HTTP Host header syntax

Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com.

This section describes the latest revision of this action. We recommend that you use this revised API operation for application development. For backward compatibility, Amazon S3 continues to support the prior version of this API operation, ListObjects.

The following operations are related to ListObjectsV2:

• GetObject

• PutObject

• CreateBucket

Implementations

impl ListObjectsV2FluentBuilder

pub fn as_input(&self) -> &ListObjectsV2InputBuilder

Access the ListObjectsV2 as a reference.

pub async fn send( self, ) -> Result<ListObjectsV2Output, SdkError<ListObjectsV2Error, HttpResponse>>

Sends the request and returns the response.

If an error occurs, an SdkError will be returned with additional details that can be matched against.

By default, any retryable failures will be retried twice. Retry behavior is configurable with the RetryConfig, which can be set when configuring the client.

pub fn customize( self, ) -> CustomizableOperation<ListObjectsV2Output, ListObjectsV2Error, Self>

Consumes this builder, creating a customizable operation that can be modified before being sent.

pub fn into_paginator(self) -> ListObjectsV2Paginator

Create a paginator for this request

Paginators are used by calling send().await which returns a PaginationStream.

pub fn bucket(self, input: impl Into<String>) -> Self

Directory buckets - When you use this operation with a directory bucket, you must use virtual-hosted-style requests in the format Bucket_name.s3express-az_id.region.amazonaws.com. Path-style requests are not supported. Directory bucket names must be unique in the chosen Availability Zone. Bucket names must follow the format bucket_base_name--az-id--x-s3 (for example, DOC-EXAMPLE-BUCKET--usw2-az1--x-s3). For information about bucket naming restrictions, see Directory bucket naming rules in the Amazon S3 User Guide.

Access points - When you use this action with an access point, you must provide the alias of the access point in place of the bucket name or specify the access point ARN. When using the access point ARN, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.Region.amazonaws.com. When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide.
