1//! FFI bindings to ARPACK-NG.
2//!
3//! The bindings are pre-generated by `bindgen` against `<arpack/arpack.h>`
4//! from ARPACK-NG (the `_c` C-callable wrappers introduced in 3.8.0).
5//! Linking is handled by `build.rs` via `pkg-config`.
6//!
7//! No safety wrappers live here — see the sibling `arpack` crate for the
8//! safe Rust API.
