Crate rlvgl_core 

Core runtime types and utilities for the rlvgl UI toolkit.

This crate exposes the building blocks used by higher-level widgets and platform backends. It is intended to be usable in no_std environments and therefore avoids allocations where possible.

Widgets are organized into a tree of WidgetNode values which receive Events and draw themselves via a Renderer implementation.

Note: Event and Renderer are externally supplied types, not defined in this crate.
