Native HarmonyOS Application Development Based on Rust + Makepad on OHOS

Two short presentations in one session: 1. Adaptation of Rust in native HarmonyOS application development and sharing of usage experience. 2. OpenHarmony provides the XCommonent component for graphics drawing and media data writing, and also provides callback functions for interface operation related events. Using these two capabilities, the EGL instructions generated in Makepad can be output to XCommonent to complete the display of graphics, and by registering the XCommonent operation event callback function, the screen operation events and screen coordinates can be converted into Makepad internal events and coordinates.
