Copy objects using OSS SDK for Go 2.0 - Object Storage Service

OSS SDK for Go 2.0 provides a set of distinct APIs for copying objects, catering to a range of use cases from simple, synchronous copies to large-scale, resumable multipart operations.

Type	API	Description
Copy an object (OSS SDK for Go 2.0)	Client.CopyObject	Suitable only for copying objects smaller than 5 GiB.
Multipart copy (OSS SDK for Go 2.0)	APIs for multipart copy: Client.InitiateMultipartUpload Client.UploadPartCopy Client.CompleteMultipartUpload	Supports copying objects larger than 5 GiB. This operation does not support the (x-oss-metadata-directive) or (x-oss-tagging-directive) parameters. Therefore, metadata and tags are not automatically copied from the source object. To add metadata or tags to the destination object, you must explicitly specify them in the copy request.
Copier (OSS SDK for Go 2.0)	APIs for the Copier: Copier.Copy	Provides a generic copy API that hides the differences and implementation details of underlying APIs. It can automatically select an appropriate API to copy an object based on the copy request parameters.
