//! rpmbuild library (i.e. `librpmbuild.so`) FFI bindings.
//!
//! Automatically generated by bindgen.
//!
//! This crate isn't intended to be used directly, but instead provides the
//! low-level binding which is used by the idiomatic librpm crate.

/// Bindings to librpmbuild.so
include!(concat!(env!("OUT_DIR"), "/binding.rs"));

// WARNING: potentially unsafe hax ahead!
// TODO: whitelist functions we need so `clock_adjtime` isn't in the binding
//
// `struct timex` (defined manually below) is problematic because the bindgen
// version includes a 352-bit bitfield type for `_bitfield_1`:
//
//     __BindgenBitfieldUnit<[u8; 44], u8>
//
// bindgen bounds the traits of the generic storage type for its bitfield
// units on `AsRef` and `AsMut`, which do not have blanket impls for `[T; N]`
// where N > 32.
//
// To work around the problem, we blacklist the type in `build.rs`, and
// include a (hopefully) equivalent one which actually compiles, namely by
// removing the `__BindgenBitfieldUnit` wraper around `[u8; 44]`, which
// should hopefully(???) result in an equivalent-sized type.
//
// `struct timex` is used only one place in the generated binding: as a
// parameter to `clock_adjtime`:
//
//     extern "C" {
//         pub fn clock_adjtime(
//             __clock_id: __clockid_t,
//            __utx: *mut timex
//         ) -> ::std::os::raw::c_int;
//     }
//
// If we could blacklist `clock_adjtime` from the binding, we wouldn't need this
// manually tweaked copy-and-paste definition of `struct timex`.
//
// Ideally we should probably switch to using `whitelisted_functions` and only
// include functions we actually intend to bind in the binding.
