Which issue does this PR close?
N/A. No existing issue tracks this service implementation.
Rationale for this change
Provide a standalone Google Cloud Storage gRPC service without depending on the
google-cloud-storageclient crate. The service uses OpenDAL existing Google credential providers and a generated Tonic client for the retained Storage v2 API surface.What changes are included in this PR?
Add the optional
opendal-service-gcs-grpccrate and register theservices-gcs-grpcfacade feature andgcs-grpcURI scheme. The service implements stat, read, write, delete, list, and copy operations. Writes use a finite non-resumableWriteObjectstream for one-shot uploads and GCS resumable writes when OpenDAL supplies multiple writes.Add a cropped Storage v2 proto, generated client, pinned upstream descriptor, and generator-side compatibility validation for retained methods and messages.
Add GCS gRPC behavior-test setup backed by the existing GCS test credentials.
Are there any user-facing changes?
Yes. Users can enable
services-gcs-grpcand construct the service withGcsGrpcor thegcs-grpc://bucket/rootURI scheme.AI Usage Statement
AI materially assisted implementation and test drafting under human-directed design review. The contributor reviewed the submitted behavior and remains responsible for the changes and claims.
