3//! LP Parser - A Linear Programming File Parser
4//!
5//! This crate provides robust parsing capabilities for Linear Programming (LP)
6//! files using LALRPOP parser generator. It supports multiple industry-standard
7//! LP file formats and offers comprehensive features for optimisation problems.
8//!
9//! # Features
10//!
11//! - Zero-copy parsing with lifetime management
12//! - Support for multiple LP file format specifications
13//! - Comprehensive parsing of all standard LP file components
14//! - Optional serialisation and diff tracking
15//!
16//! # Quick Start
17//!
18//! ```rust
19//! use std::path::Path;
20//!
21//! use lp_parser::{parser::parse_file, LpProblem};
22//!
23//!
24//! fn main() -> Result<(), Box<dyn std::error::Error>> {
25//!     let content = parse_file(Path::new("problem.lp"))?;
26//!     let problem = LpProblem::parse(&content)?;
27//!     println!("Problem name: {:?}", problem.name());
28//!     Ok(())
29//! }
30//! ```
