rlvgl-core

Package: rlvgl-core

rlvgl-core is the foundation crate for the rlvgl workspace. It defines the runtime model used by widgets, applications, renderers, and platform backends.

Main Areas

• widget tree and composition via Widget and WidgetNode
• event dispatch and application integration via event and application
• renderer-facing drawing abstractions in renderer
• style, theme, animation, and font utilities
• optional plugin modules for assets and integrations such as png, jpeg, gif, qrcode, fontdue, lottie, canvas, fatfs, nes, and apng

Target Model

rlvgl-core is no_std by default. Host-side decoders and similar integrations are feature-gated, and image/QR decoding features are automatically kept off on target_os = "none" where those dependencies are not intended to be pulled into embedded binaries.

Where It Is Used

• rlvgl re-exports it as part of the top-level toolkit
• rlvgl-widgets builds concrete widgets on top of it
• rlvgl-platform provides hardware and simulator backends for it
• rlvgl-ui layers higher-level components and theming on top
• rlvgl-app-demo uses it as the application/runtime contract

Typical Use

Reach for rlvgl-core when you are building custom widgets, writing a renderer or display backend, or integrating the toolkit into a new runtime. Most end applications will use it indirectly through rlvgl, rlvgl-widgets, or rlvgl-ui.
