//! # CNVX Parse
//!
//! This crate provides simple parsers for various LP file formats, including AMPL, GMPL, and MPS,
//! built on top of [`cnvx_core`]. It defines a common [`LanguageParser`] trait and specific parsers for
//! each format.
//!
//! # Modules
//!
//! - [`ampl`]: Parser for AMPL format.
//! - [`gmpl`]: Parser for GMPL format.
//! - [`mps`]: Parser for MPS format.

    let model = match file_type {
        "ampl" => AMPLLanguage::new().parse(contents)?,

        "mps" => MPSLanguage::new().parse(contents)?,
