Unofficial Rust driver for WeAct Studio e-paper displays.
The driver exposes both write access to the screen frame buffers and higher-level embedded-graphics support.
By default this driver uses async. If you prefer to use a blocking API instead you can enable the blocking feature.

[^1]: Allows updating part of the screen buffer to save IO time and potentially memory.
[^2]: Refresh the screen without flickering the screen a few times.
