//! Generators, solvers and difficulty raters for pencil puzzles.
//!
//! Each genre is a module, behind a feature of the same name. All genres are
//! enabled by default. To compile fewer genres, turn off default features and
//! enable the ones you need.
//!
//! ```
//! # #[cfg(feature = "kakurasu")] {
//! use pencil_puzzles::Difficulty;
//! use pencil_puzzles::kakurasu::{self, GenerateOptions};
//!
//! let mut options = GenerateOptions::new("6x6".parse().unwrap(), 42);
//! options.difficulty = Some(Difficulty::Hard);
//! let generated = kakurasu::generate(&options, &pencil_puzzles_core::Budget::unlimited()).unwrap();
//! assert_eq!(generated.rating.level, Difficulty::Hard);
//! # }
//! ```
//!
//! # Features
//!
//! - `all-genres` (default): every genre.
//! - One feature per genre, such as `kakurasu`.
//! - `serde`: implements `Serialize` and `Deserialize` for each genre's
//!   puzzles, solutions and ratings.
