Crate pure_onnx_ocr 

Pure ONNX OCR

A Pure Rust OCR pipeline that mirrors the PaddleOCR DBNet + SVTR stack. The crate exposes ergonomic builders and processing stages that let you load ONNX models, prepare image batches, and decode recognition logits without any C/C++ dependencies.

Most consumers interact with OcrEngineBuilder to construct an OcrEngine, then call OcrEngine::run_from_path or OcrEngine::run_from_image. Lower-level modules remain available when you need to plug specific stages into an existing pipeline.
