Implementations

impl Builder

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

The name of the bucket containing the object.

When using this action with an access point, 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.

When using this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form AccessPointName-AccountId.outpostID.s3-outposts.Region.amazonaws.com. When using this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts bucket ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see Using Amazon S3 on Outposts in the Amazon S3 User Guide.

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

The name of the bucket containing the object.

When using this action with an access point, 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.

When using this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form AccessPointName-AccountId.outpostID.s3-outposts.Region.amazonaws.com. When using this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts bucket ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see Using Amazon S3 on Outposts in the Amazon S3 User Guide.

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

Return the object only if its entity tag (ETag) is the same as the one specified; otherwise, return a 412 (precondition failed) error.

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

Return the object only if its entity tag (ETag) is the same as the one specified; otherwise, return a 412 (precondition failed) error.

pub fn if_modified_since(self, input: DateTime) -> Self

Return the object only if it has been modified since the specified time; otherwise, return a 304 (not modified) error.

pub fn set_if_modified_since(self, input: Option<DateTime>) -> Self

Return the object only if it has been modified since the specified time; otherwise, return a 304 (not modified) error.

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

Return the object only if its entity tag (ETag) is different from the one specified; otherwise, return a 304 (not modified) error.

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

Return the object only if its entity tag (ETag) is different from the one specified; otherwise, return a 304 (not modified) error.

pub fn if_unmodified_since(self, input: DateTime) -> Self

Return the object only if it has not been modified since the specified time; otherwise, return a 412 (precondition failed) error.

pub fn set_if_unmodified_since(self, input: Option<DateTime>) -> Self

Return the object only if it has not been modified since the specified time; otherwise, return a 412 (precondition failed) error.

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

The object key.

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

The object key.

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

Because HeadObject returns only the metadata for an object, this parameter has no effect.

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

Because HeadObject returns only the metadata for an object, this parameter has no effect.

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

VersionId used to reference a specific version of the object.

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

VersionId used to reference a specific version of the object.

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

Specifies the algorithm to use to when encrypting the object (for example, AES256).

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

Specifies the algorithm to use to when encrypting the object (for example, AES256).

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

Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon S3 does not store the encryption key. The key must be appropriate for use with the algorithm specified in the x-amz-server-side-encryption-customer-algorithm header.

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

Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon S3 does not store the encryption key. The key must be appropriate for use with the algorithm specified in the x-amz-server-side-encryption-customer-algorithm header.

pub fn sse_customer_key_md5(self, input: impl Into<String>) -> Self

Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

pub fn set_sse_customer_key_md5(self, input: Option<String>) -> Self

Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

pub fn request_payer(self, input: RequestPayer) -> Self

Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide.

pub fn set_request_payer(self, input: Option<RequestPayer>) -> Self

Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide.

pub fn part_number(self, input: i32) -> Self

Part number of the object being read. This is a positive integer between 1 and 10,000. Effectively performs a 'ranged' HEAD request for the part specified. Useful querying about the size of the part and the number of parts in this object.

pub fn set_part_number(self, input: Option<i32>) -> Self

Part number of the object being read. This is a positive integer between 1 and 10,000. Effectively performs a 'ranged' HEAD request for the part specified. Useful querying about the size of the part and the number of parts in this object.

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

The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).

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

The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).

pub fn checksum_mode(self, input: ChecksumMode) -> Self

To retrieve the checksum, this parameter must be enabled.

In addition, if you enable ChecksumMode and the object is encrypted with Amazon Web Services Key Management Service (Amazon Web Services KMS), you must have permission to use the kms:Decrypt action for the request to succeed.

pub fn set_checksum_mode(self, input: Option<ChecksumMode>) -> Self

To retrieve the checksum, this parameter must be enabled.

In addition, if you enable ChecksumMode and the object is encrypted with Amazon Web Services Key Management Service (Amazon Web Services KMS), you must have permission to use the kms:Decrypt action for the request to succeed.

pub fn build(self) -> Result<HeadObjectInput, BuildError>

Consumes the builder and constructs a HeadObjectInput.
