//! # RustO! - Pure Rust OCR Library
//!
//! RustO! is a high-performance OCR library written in pure Rust,
//! powered by PaddleOCR models with MNN inference engine.
//!
//! ## Features
//!
//! - **Pure Rust**: Zero OpenCV dependency (optional OpenCV backend available)
//! - **High Accuracy**: 99.3% parity with OpenCV-based implementations
//! - **Fast Performance**: Optimized with LTO and aggressive compilation settings
//! - **Cross-Platform**: Linux, macOS, Windows, Android, iOS support
//! - **Memory Safe**: Leverages Rust's safety guarantees
//!
//! ## Quick Start
//!
//! ```rust,no_run
//! use rusto::RustO;
//!
//! let mut ocr = RustO::new_ppv5("models/det.mnn", "models/rec.mnn", "models/dict.txt")?;
//! let result = ocr.run("image.jpg")?;
//!
//! for (text, score) in result.txts.iter().zip(result.scores.iter()) {
//!     println!("{}: {:.3}", text, score);
//! }
//! # Ok::<(), Box<dyn std::error::Error>>(())
//! ```
