- Pluggable backend architecture: all backends implement the OcrBackend trait
|
|
- Backend independence: switching backends must not require API changes
|
|
- Tesseract is the default backend (native C FFI via leptess)
|
|
- Python backends (EasyOCR, PaddleOCR): use tokio::task::spawn_blocking, release GIL for Rust work
|
|
- Graceful degradation: if preferred backend unavailable, fall back to next available
|
|
- All backends must return structured results with confidence scores
|
|
- Document installation requirements and troubleshooting for each backend
