1//! # Backward Chaining Module
2//!
3//! Goal-driven reasoning system for rust-rule-engine.
4//! This module is only available when the `backward-chaining` feature is enabled.
5//!
6//! ## Overview
7//!
8//! Backward chaining works by starting from a goal and working backwards
9//! to find rules and facts that can prove that goal.
10//!
11//! ## Example
12//!
13//! ```ignore
14//! use rust_rule_engine::backward::*;
15//!
16//! let bc_engine = BackwardEngine::new(kb);
17//! let result = bc_engine.query("User.IsVIP == true", &facts)?;
18//!
19//! if result.provable {
20//!     println!("Goal is provable!");
21//!     println!("Proof: {:?}", result.proof_trace);
22//! }
23//! ```
