Crate Map

Use the smallest public surface that matches your job.

Recommended Starting Point

• univis_ui is the default dependency for most applications.
• univis_ui::prelude is the recommended day-to-day import surface.
• The facade prelude includes the canonical root, layout, interaction, style, and built-in widget APIs.
• Deprecated compatibility wrappers are intentionally excluded from the prelude. Use explicit paths such as univis_ui::layout::layout_system::{UScreenRoot, UWorldRoot} only when migrating older code.

When To Depend On Each Crate

• univis_ui: use this when you want one plugin and one import story for the full stack.
• univis_ui_engine: use this when you need roots, layout, rendering sync, or custom widget/runtime work without the full facade.
• univis_ui_interaction: use this when you need picking and UInteraction-driven feedback on top of engine roots.
• univis_ui_widgets: use this when you want the built-in controls but still manage plugin composition yourself.
• univis_ui_style: use this when you only need shared theme resources, fonts, icons, or text styles.

Prelude Policy

• prelude means the stable recommended import surface for everyday use.
• Named modules such as layout, render, interaction, and widget are advanced but still public.
• Deprecated compatibility wrappers stay on explicit paths instead of the default import story.
