Struct aws_sdk_s3::operation::get_bucket_policy::builders::GetBucketPolicyFluentBuilder

pub struct GetBucketPolicyFluentBuilder { /* private fields */ }

Fluent builder constructing a request to GetBucketPolicy.

Returns the policy of a specified bucket.

Directory buckets - For directory buckets, you must make requests for this API operation to the Regional endpoint. These endpoints support path-style requests in the format https://s3express-control.region_code.amazonaws.com/bucket-name . Virtual-hosted-style requests aren't supported. For more information, see Regional and Zonal endpoints in the Amazon S3 User Guide.

Permissions

If you are using an identity other than the root user of the Amazon Web Services account that owns the bucket, the calling identity must both have the GetBucketPolicy permissions on the specified bucket and belong to the bucket owner's account in order to use this operation.

If you don't have GetBucketPolicy permissions, Amazon S3 returns a 403 Access Denied error. If you have the correct permissions, but you're not using an identity that belongs to the bucket owner's account, Amazon S3 returns a 405 Method Not Allowed error.

To ensure that bucket owners don't inadvertently lock themselves out of their own buckets, the root principal in a bucket owner's Amazon Web Services account can perform the GetBucketPolicy, PutBucketPolicy, and DeleteBucketPolicy API actions, even if their bucket policy explicitly denies the root principal's access. Bucket owner root principals can only be blocked from performing these API actions by VPC endpoint policies and Amazon Web Services Organizations policies.

• General purpose bucket permissions - The s3:GetBucketPolicy permission is required in a policy. For more information about general purpose buckets bucket policies, see Using Bucket Policies and User Policies in the Amazon S3 User Guide.

• Directory bucket permissions - To grant access to this API operation, you must have the s3express:GetBucketPolicy permission in an IAM identity-based policy instead of a bucket policy. Cross-account access to this API operation isn't supported. This operation can only be performed by the Amazon Web Services account that owns the resource. For more information about directory bucket policies and permissions, see Amazon Web Services Identity and Access Management (IAM) for S3 Express One Zone in the Amazon S3 User Guide.

Implementations

impl GetBucketPolicyFluentBuilder

pub fn as_input(&self) -> &GetBucketPolicyInputBuilder

Access the GetBucketPolicy as a reference.

pub async fn send( self, ) -> Result<GetBucketPolicyOutput, SdkError<GetBucketPolicyError, 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<GetBucketPolicyOutput, GetBucketPolicyError, Self>

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

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

The bucket name to get the bucket policy for.

Directory buckets - When you use this operation with a directory bucket, you must use path-style requests in the format https://s3express-control.region_code.amazonaws.com/bucket-name . Virtual-hosted-style requests aren't supported. Directory bucket names must be unique in the chosen Availability Zone. Bucket names must also 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 API operation with an access point, provide the alias of the access point in place of the bucket name.

Object Lambda access points - When you use this API operation with an Object Lambda access point, provide the alias of the Object Lambda access point in place of the bucket name. If the Object Lambda access point alias in a request is not valid, the error code InvalidAccessPointAliasError is returned. For more information about InvalidAccessPointAliasError, see List of Error Codes.

Access points and Object Lambda access points are not supported by directory buckets.

pub fn set_bucket(self, input: Option<String>) -> Self

The bucket name to get the bucket policy for.

Object Lambda access points - When you use this API operation with an Object Lambda access point, provide the alias of the Object Lambda access point in place of the bucket name. If the Object Lambda access point alias in a request is not valid, the error code InvalidAccessPointAliasError is returned. For more information about InvalidAccessPointAliasError, see List of Error Codes.

Access points and Object Lambda access points are not supported by directory buckets.

pub fn get_bucket(&self) -> &Option<String>

The bucket name to get the bucket policy for.

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

The account ID of the expected bucket owner. If the account ID that you provide does not match the actual owner of the bucket, the request fails with the HTTP status code 403 Forbidden (access denied).

For directory buckets, this header is not supported in this API operation. If you specify this header, the request fails with the HTTP status code 501 Not Implemented.

pub fn set_expected_bucket_owner(self, input: Option<String>) -> Self

The account ID of the expected bucket owner. If the account ID that you provide does not match the actual owner of the bucket, the request fails with the HTTP status code 403 Forbidden (access denied).

For directory buckets, this header is not supported in this API operation. If you specify this header, the request fails with the HTTP status code 501 Not Implemented.
