sansheng 0.5.0

//! 三生（Sansheng）：三值推理工具箱的伞包。
//!
//! 内部实现分布在 `trit-*` crate；这里提供统一入口：
//!
//! ```
//! use sansheng::{equivalent_symbolic, Algebra, Parser};
//! let a = Parser::parse("a & (b | c)").unwrap();
//! let b = Parser::parse("(a & b) | (a & c)").unwrap();
//! assert!(equivalent_symbolic(&a, &b, Algebra::Kleene).unwrap().equivalent);
//! ```
//!
//! 量化按 **trit** 取值（`{0,1,X}`）解释，而不是按两根布尔导轨：
//!
//! ```
//! use std::collections::HashSet;
//! use sansheng::{Algebra, Parser, Quantifier, quantify_bdd};
//! let e = Parser::parse("a | !a").unwrap();
//! let vars = e.variables();
//! let q = quantify_bdd(&e, &vars, Quantifier::Forall, Algebra::Kleene, &HashSet::new()).unwrap();
//! assert!(!q.is_valid(), "三值域下 a=X 时 a|!a 不为真");
//! ```
