benroeder opened a new issue, #7203:
URL: https://github.com/apache/opendal/issues/7203
## Describe the bug
The Swift backend implements the `copy()` method in `Access` (via
`swift_copy` using PUT with `X-Copy-From`), but the `Capability` struct in
`backend.rs` does not include `copy: true`.
OpenDAL's framework checks capabilities before dispatching operations to the
backend. Without the flag, any `copy()` call is rejected with a "not supported"
error before the implementation is ever reached.
## Steps to Reproduce
1. Configure a Swift backend
2. Attempt `op.copy("source.txt", "dest.txt").await`
3. Operation fails with capability error despite the backend having a
working `copy()` implementation
## Expected Behavior
Server-side copy should succeed, since the implementation exists and Swift
supports COPY via `PUT` with `X-Copy-From` header.
## Additional Context
One-line fix: add `copy: true` to the `Capability` struct in
`core/services/swift/src/backend.rs`.
