//! Raw FFI bindings for SuiteSparse:GraphBLAS and LAGraph.
//!
//! This crate is a `*-sys` crate in the Rust ecosystem sense: it owns the
//! native build (link directives in `build.rs`) and exposes the bindgen-
//! generated symbols verbatim. Higher-level safe wrappers, RAII guards, and
//! Rust APIs live in the `pathrex` crate.
//!
//! Bindings are generated from the LAGraph headers in `deps/LAGraph/include`
//! and the system-installed `GraphBLAS.h`. The generated file
//! `src/lagraph_sys_generated.rs` is checked in; regenerate it with
//! `cargo build --features regenerate-bindings` (requires `libclang`).

    non_camel_case_types,
