#![allow(clippy::multiple_crate_versions)]

//! LP Parser - A Linear Programming File Parser
//!
//! This crate provides robust parsing capabilities for Linear Programming (LP)
//! files using LALRPOP parser generator. It supports multiple industry-standard
//! LP file formats and offers comprehensive features for optimisation problems.
//!
//! # Features
//!
//! - Zero-copy parsing with lifetime management
//! - Support for multiple LP file format specifications
//! - Comprehensive parsing of all standard LP file components
//! - Optional serialisation and diff tracking
//!
//! # Quick Start
//!
//! ```rust
//! use std::path::Path;
//!
//! use lp_parser::{parser::parse_file, LpProblem};
//!
//!
//! fn main() -> Result<(), Box<dyn std::error::Error>> {
//!     let content = parse_file(Path::new("problem.lp"))?;
//!     let problem = LpProblem::parse(&content)?;
//!     println!("Problem name: {:?}", problem.name());
//!     Ok(())
//! }
//! ```
