This crate contains the low-level unsafe Rust -> C FFI bindings to hwloc, that are used to implement the safe hwlocality bindings.
Like any C API, these low-level bindings are highly unsafe to use, and it is advised that you use the safe bindings instead whenever possible.
If you encounter any issue with the safe bindings that prevents you from using them and forces you to use the unsafe C API directly, please report it to me.
