This repository implements the UWB D-Bus daemon, including the service written in Rust, the D-Bus and upstart configuration files, D-Bus interface and protobuf definition. The D-Bus daemon defines the D-Bus interface, initiates the UWB service from the uwb_core library, and delegates the requests to the UWB service.
Officially, this project is built by ChromeOS gentoo build system. However, the D-Bus daemon binary could also be built by cargo. Building the rust code by cargo could validate whether the code is compilable quickly.
It follows the normal ChromeOS development flow.

THe uwb_uci_packets packet, which is a dependency of the D-Bus daemon, depends on the bluetooth_packetgen binary. So we should install the bluetooth_packetgen binary before building the D-Bus daemon by cargo.

When initiating the UWB service from the uwb_core library, we need to inject the UCI HAL into it. The HAL implementation should be placed at src/uci_hal_impl.rs.
