This release has an MSRV of 1.82.

Overview

ui-events v0.2.0 is a major overhaul to the ergonomics of event handling (particularly handling scale).
It also debuts the new ui-input-state crate, providing reusable keyboard and pointer state tracking.

This release includes contributions from five developers, with three newcomers @nicoburns, @arthur-fontaine, and @jrmoulton.
Thank you for your help!

Highlights

• New crate: ui-input-state — initial release, providing KeyboardState, PrimaryPointerState, which provide useful stateful information about inputs.
• Pointer gestures: Added pinch and rotate gesture support via PointerGesture and PointerGestureEvent.
• Scale factor support: PointerState now carries the scale factor, for easy translation.
• Performance improvements: Reduced allocations and simplified event data structures.
• Better consistency and ergonomics: Pointer event variants refactored for clarity and flexibility.
• Platform improvements: ui-events-winit now does scale-aware tap/click counting.
