// Uploads a part by copying data from an existing object as data source. You
// specify the data source by adding the request header x-amz-copy-source in your
// request and a byte range by adding the request header x-amz-copy-source-range in
// your request. For information about maximum and minimum part sizes and other
// multipart upload specifications, see Multipart upload limits
// (https://docs.aws.amazon.com/AmazonS3/latest/userguide/qfacts.html) in the
// Amazon S3 User Guide. Instead of using an existing object as part data, you
// might use the UploadPart
// (https://docs.aws.amazon.com/AmazonS3/latest/API/API_UploadPart.html) action and
// provide data in your request. You must initiate a multipart upload before you
// can upload any part. In response to your initiate request. Amazon S3 returns a
// unique identifier, the upload ID, that you must include in your upload part
// request. For more information about using the UploadPartCopy operation, see the
// following:
//
// * For conceptual information about multipart uploads, see Uploading
// Objects Using Multipart Upload
// (https://docs.aws.amazon.com/AmazonS3/latest/dev/uploadobjusingmpu.html) in the
// Amazon S3 User Guide.
//
// * For information about permissions required to use the
// multipart upload API, see Multipart Upload and Permissions
// (https://docs.aws.amazon.com/AmazonS3/latest/dev/mpuAndPermissions.html) in the
// Amazon S3 User Guide.
//
// * For information about copying objects using a single
// atomic action vs. a multipart upload, see Operations on Objects
// (https://docs.aws.amazon.com/AmazonS3/latest/dev/ObjectOperations.html) in the
// Amazon S3 User Guide.
//
// * For information about using server-side encryption with
// customer-provided encryption keys with the UploadPartCopy operation, see
// CopyObject (https://docs.aws.amazon.com/AmazonS3/latest/API/API_CopyObject.html)
// and UploadPart
// (https://docs.aws.amazon.com/AmazonS3/latest/API/API_UploadPart.html).
//
// Note the
// following additional considerations about the request headers
// x-amz-copy-source-if-match, x-amz-copy-source-if-none-match,
// x-amz-copy-source-if-unmodified-since, and
// x-amz-copy-source-if-modified-since:
//
// * Consideration 1 - If both of the
// x-amz-copy-source-if-match and x-amz-copy-source-if-unmodified-since headers are
// present in the request as follows: x-amz-copy-source-if-match condition
// evaluates to true, and; x-amz-copy-source-if-unmodified-since condition
// evaluates to false; Amazon S3 returns 200 OK and copies the data.
//
// *
// Consideration 2 - If both of the x-amz-copy-source-if-none-match and
// x-amz-copy-source-if-modified-since headers are present in the request as
// follows: x-amz-copy-source-if-none-match condition evaluates to false, and;
// x-amz-copy-source-if-modified-since condition evaluates to true; Amazon S3
// returns 412 Precondition Failed response code.
//
// Versioning If your bucket has
// versioning enabled, you could have multiple versions of the same object. By
// default, x-amz-copy-source identifies the current version of the object to copy.
// If the current version is a delete marker and you don't specify a versionId in
// the x-amz-copy-source, Amazon S3 returns a 404 error, because the object does
// not exist. If you specify versionId in the x-amz-copy-source and the versionId
// is a delete marker, Amazon S3 returns an HTTP 400 error, because you are not
// allowed to specify a delete marker as a version for the x-amz-copy-source. You
// can optionally specify a specific version of the source object to copy by adding
// the versionId subresource as shown in the following example: x-amz-copy-source:
// /bucket/object?versionId=version id Special Errors
//
// * Code: NoSuchUpload
//
// *
// Cause: The specified multipart upload does not exist. The upload ID might be
// invalid, or the multipart upload might have been aborted or completed.
//
// * HTTP
// Status Code: 404 Not Found
//
// * Code: InvalidRequest
//
// * Cause: The specified copy
// source is not supported as a byte-range copy source.
//
// * HTTP Status Code: 400
// Bad Request

	// (https://docs.aws.amazon.com/AmazonS3/latest/userguide/access-points.html):
	//
	// *
	// For objects not accessed through an access point, specify the name of the source
	// bucket and key of the source object, separated by a slash (/). For example, to
	// copy the object reports/january.pdf from the bucket awsexamplebucket, use
	// awsexamplebucket/reports/january.pdf. The value must be URL-encoded.
	//
	// * For
	// objects accessed through access points, specify the Amazon Resource Name (ARN)
	// of the object as accessed through the access point, in the format
	// arn:aws:s3:::accesspoint//object/. For example, to copy the object
	// reports/january.pdf through access point my-access-point owned by account
	// 123456789012 in Region us-west-2, use the URL encoding of
	// arn:aws:s3:us-west-2:123456789012:accesspoint/my-access-point/object/reports/january.pdf.
	// The value must be URL encoded. Amazon S3 supports copy operations using access
	// points only when the source and destination buckets are in the same Amazon Web
	// Services Region. Alternatively, for objects accessed through Amazon S3 on
	// Outposts, specify the ARN of the object as accessed in the format
	// arn:aws:s3-outposts:::outpost//object/. For example, to copy the object
	// reports/january.pdf through outpost my-outpost owned by account 123456789012 in

	// arn:aws:s3-outposts:us-west-2:123456789012:outpost/my-outpost/object/reports/january.pdf.

	// awsexamplebucket/reports/january.pdf?versionId=QUpfdndhfd8438MNFDN93jdnJFkdmqnh893).
