D-Bus is a message bus system, a simple way for applications to talk to one another. In addition to interprocess communication, D-Bus helps coordinate process lifecycle; it makes it simple and reliable to code a "single instance" application or daemon, and to launch applications and daemons on demand when their services are needed.

The goal of this umbrella project is to provide safe and modern D-Bus implemententations, using the Rust programming language. This initiative is split into two main projects:

• zbus: A pure Rust D-Bus library, that focuses on ease of use. zbus is already a well-established library, and is used in production by several projects and companies.

• busd: A D-Bus daemon/broker, that aims to be a drop-in replacement for the reference implementation of D-Bus, dbus-daemon and dbus-broker. busd is not yet ready for production use.
