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.

See the examples folder for complete usage examples.
blocking: Replaces the API with a blocking version. This disables the async API so you cannot use both in the same project.graphics: Enables embedded-graphics support. Enabled by default.This driver is based on the following crates:
