Since it's pure Rust, it's much easier to build for multiple platforms (Linux, Mac and Windows being the primary targets) than other D-Bus brokers. ## Status Alpha. It's not ready for production use yet. Only the essentials are in place. ## Installation & Use Currently, we can only offer installation from source: ```bash cargo install -f busd ``` Running a session instance is super easy: ```bash busd --print-address ``` `--print-address` will print the address of the bus to stdout. You can then use that address to connect to the bus: ```bash export DBUS_SESSION_BUS_ADDRESS="unix:path=/run/user/1000/bus,guid=d0af79a44c000ce7985797ba649dbc05" busctl --user introspect org.freedesktop.DBus /org/freedesktop/DBus busctl --user list ``` Since auto-starting of services is not yet implemented, you'll have to start services manually: ```bash # Probably not the best example since the service just exits after a call to it. /usr/libexec/dleyna-renderer-service & busctl call --user com.intel.dleyna-renderer /com/intel/dLeynaRenderer com.intel.dLeynaRenderer.Manager GetRenderers ``` ## The plan ### Full compatibility with the D-Bus specification Implement all features that manadated and recommended by the [specification]. ### Additional Header Fields While the D-Bus spec does not allow custom header fields in messages, `busd` will still support a few additional on-demand (only) fields, that are useful for certain applications. One example is addition of [peer credentials] on every message, which can avoid round-trips on the bus. ## License [MIT](LICENSE-MIT) [specification]: https://dbus.freedesktop.org/doc/dbus-specification.html [peer credentials]: https://github.com/dbus2/busd/issues/29
