Crate lp_parser_rs 

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

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(())
}
