presolve_compiler/

lib.rs

//! Core compiler data structures for the first `Presolve` learning slice.
//!
//! This crate deliberately does **not** parse TSX yet. It records a source summary,
//! spans, obvious declarations, and diagnostics. That gives the project a stable
//! place to learn compiler fundamentals before choosing a real parser backend.
