1//! Pure Rust PAR2 verify and repair.
2//!
3//! The first Rust crate with full PAR2 repair support. Implements GF(2^16)
4//! arithmetic with the PAR2-mandated polynomial `0x1100B` and Reed-Solomon
5//! decoding for block-level repair.
6//!
7//! # Usage
8//!
9//! ```no_run
10//! use std::path::Path;
11//!
12//! let par2_path = Path::new("/downloads/movie/movie.par2");
13//! let job_dir = Path::new("/downloads/movie");
14//!
15//! // Parse the PAR2 index file
16//! let file_set = rust_par2::parse(par2_path).unwrap();
17//!
18//! // Verify all files
19//! let result = rust_par2::verify(&file_set, job_dir);
20//!
21//! if result.all_correct() {
22//!     println!("All files intact");
23//! } else if result.repair_possible {
24//!     // Repair damaged/missing files
25//!     let repair = rust_par2::repair(&file_set, job_dir).unwrap();
26//!     println!("{repair}");
27//! }
28//! ```
