//! Low level FFI bindings to [`libnftnl`], a userspace library providing a low-level netlink
//! programming interface (API) to the in-kernel nf_tables subsystem.
//!
//! See [`rustables`] for a higher level safe abstraction.
//!
//! # Linking to libmnl and libnftnl
//!
//! By default this crate uses pkg-config to find and link to its C dependencies, [`libmnl`] and
//! [`libnftnl`]. To manually configure where to look for these libraries, set the environment
//! variables `LIBMNL_LIB_DIR` and `LIBNFTNL_LIB_DIR` to point to the directories where `libmnl.so`
//! (or `libmnl.a`) and `libnftnl.so` (or `libnftnl.a`) reside.
//!
//! # Selecting version of `libnftnl`
//!
//! This crate has bindings for most versions of [`libnftnl`]. All bindings are generated by
//! [`bindgen`] via the `generate_bindings.sh` script in this repository.
//!
//! Only one version of `libnftnl` can be exposed via this crate. By default the crate exports the
//! bindings for the oldest supported version (`libnftnl-1.0.6`). To get newer versions activate the
//! corresponding features. See `Cargo.toml` for available features/versions.
//!
//! So for example, to get bindings to `libnftnl-1.0.9` depend on this crate like this:
//! ```toml
//! [dependencies]
//! rustables-sys = { version = "0.1", features = ["nftnl-1-0-9"] }
//! ```
//!
//! [`libnftnl`]: https://netfilter.org/projects/libnftnl/
//! [`libmnl`]: https://netfilter.org/projects/libmnl/
//! [`rustables`]: https://crates.io/crates/rustables
//! [`bindgen`]: https://crates.io/crates/bindgen
