We now have bidirectional calling between Rust and C++, but we are generating two static libraries that we then link together with a tiny C++ `main.cxx`. Let's make another huge leap towards oxdiation by having Rust be the entrypoint. This way cargo natively takes care of linking the internal Rust library, and our C++ internals become the library. In other words, we've now fully inverted from "C app with internal Rust library" to "Rust binary with internal C++ library". In order to make this work though we have to finally kill the C unit tests. But mostly everything covered there is either being converted to Rust, or covered elsewhere anyways. Now as the doc comments in `main.rs` say...this is a bit awkward because all the CLI code is still in C++. Porting stuff to use e.g. `structopt` natively would be a bit of a slog. For now, we basically rely on the fact that the Rust-native CLIs are all hidden commands. Update submodule: libdnf
rpm-ostree: A true hybrid image/package system
rpm-ostree is a hybrid image/package system. It combines libostree as a base image format, and accepts RPM on both the client and server side, sharing code with the dnf project; specifically libdnf. and thus bringing many of the benefits of both together.
