 * Generates client-side getter methods that request current field value.

-clients and dispatches them to the user's implementations.

 User code must have these dependencies (per README):
 * `futures` with `async-await` feature.
 * `embassy-sync` for channels and synchronization.
+* `embassy-time` for poll method timing (only required if using poll methods).
 
 Dev dependencies include `embassy-executor` and `embassy-time` for testing.
