Summary
Adds WritableResultExt trait for Writable, mirroring the existing ReadableResultExt on the read side. This provides mutable access to signal values holding Result without needing an intermediate binding.
Methods
as_mut()-- returnsResult, giving mutable access to whichever variant the Result holds> unwrap_mut()-- returnsWritableRef, panicking if the Result isErr
Pattern
Follows the same extension trait pattern used by WritableOptionExt and ReadableResultExt:
- Blanket impl over all
W: Writable> - Uses
WriteLock::map/WriteLock::filter_mapfor mapped mutable references #[track_caller]on all methods for better panic diagnostics
Closes #5293

...xt::as_mut
Replace bare .unwrap() calls with .expect() containing a descriptive
message about the failure mode. This gives better diagnostics if the
Result variant changes between the read and write lock acquisitions.
