124-129: Consider usingas_ref()to avoid unnecessary cloningThe current implementation clones the Option's content before applying the default. While this works, it introduces unnecessary overhead when the Option contains a value.
Consider this more efficient alternative:
- sb.push_str( - self.topic_name - .clone() - .unwrap_or(CheetahString::empty()) - .as_str(), - ); + sb.push_str( + self.topic_name + .as_ref() + .map_or_else(CheetahString::empty, |s| s) + .as_str(), + );

137-137: Verify Display implementation and format compatibility
The change from debug format to display format is more idiomatic, but requires verification:
- Ensure TopicFilterType implements Display trait
- Verify if any downstream systems depend on the previous debug format
✅ Verification successful
Format change is safe - Display trait is properly implemented
TopicFilterType correctly implements the Display trait with clear string representations:
SINGLE_TAGfor SingleTag variantMULTI_TAGfor MultiTag variant
The change from debug to display format is safe as it provides a consistent string representation. No downstream dependencies were found that rely on the encoded format.
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Check if TopicFilterType implements Display
ast-grep --pattern 'impl Display for TopicFilterType'
# Find potential downstream dependencies on the encoded format
rg -l 'TopicConfig.*encode' --type rust
