Standardize code formatting across all 173 Rust source files
using rustfmt. No functional changes - purely cosmetic.
This establishes a consistent code style baseline for the
project going forward.
- Downgrade OXICLOUD_JWT_SECRET missing log from error to warn level,
since generating a random secret per session is valid behavior
- Remove unused import super::* in calendar_storage_adapter tests
- Remove unused import tokio_stream::StreamExt in compression_service tests
- Prefix unused validate_user_ownership with _ in trash_service
- Add nohup.out to .gitignore
The translation commit accidentally removed the match statement and
opening arms (match item_result, Ok(Some(item)), match item.item_type)
while keeping the body, causing a brace mismatch compilation error.
