bevy_a11y

Accessibility primitives. A small crate that exposes AccessKit types as ECS components so other crates (UI, windowing) can publish accessibility data to platform screen readers and assistive tech.

Purpose

Re-export AccessKit's Node, NodeBuilder, Role, Action, etc. as Bevy types and provide a plugin that registers them with the world. The actual integration with the OS-level a11y bus happens in bevy_winit (when accesskit_unix or platform-specific features are on).

Key abstractions

Type	File	Description
AccessibilityPlugin	crates/bevy_a11y/src/lib.rs	Adds the resources used by other crates.
AccessibilityNode	crates/bevy_a11y/src/lib.rs	Component wrapping accesskit::Node.
ManageAccessibilityUpdates	crates/bevy_a11y/src/lib.rs	Resource: whether Bevy is responsible for sending a11y updates this frame.
Focus	crates/bevy_a11y/src/lib.rs	Resource holding the currently focused entity for screen readers.

Integration points

• Depends on: accesskit, bevy_app, bevy_ecs, bevy_reflect.
• Depended on by: bevy_winit, bevy_ui, bevy_input_focus.

Entry points for modification

The crate is intentionally minimal. Most work happens in bevy_winit's a11y systems — that's where AccessKit's tree gets pushed to the OS each frame.

• bevy_winit — sends the AccessKit tree to the OS.
• bevy_ui — populates AccessibilityNode for UI elements.
