//! A Sudoku library implemented in Rust with efficient bitmasking for constraint tracking.
//!
//! This library provides a `Rustoku` struct that can solve and check 9x9 Sudoku puzzles.
//! The implementation uses bitmasks to efficiently track constraints for
//! rows, columns, and 3x3 boxes, enabling fast validation and candidate computation
//! during the solving process.
//!
//! The library also provides a `generate_board` utility to generate puzzles. The
//! output includes the matrix-like representation of the board as well as the
//! one-line representation for easy copying and pasting.
