Crate xen_animation 

A high-performance, framework-agnostic animation library for Rust.

xen-animation centralizes the lifecycle of every animated value behind a single AnimationManager: callers report the current target value each frame, and the manager takes care of starting, easing, retargeting, and finishing the transition on its own. It has no rendering or windowing dependencies, so it can be reused across GUI frameworks, game engines, or any other application that needs frame-based interpolation.

Structs

AnimValue

Generic animatable payload; every property (color, scale, opacity…) is flattened into up to 4 floats so the manager can interpolate anything without knowing what it represents.

AnimationManager

Central, Qt-style animation driver, generic over any hashable key type so it can be reused outside of any specific GUI framework. Callers never own a timer themselves; they only report their current target value and the manager owns the entire lifecycle (starting, easing, retargeting, finishing).

CubicBezier

A CSS-compatible cubic-bezier timing function. The curve’s start and end points are implicitly (0,0) and (1,1); only the two control points are stored, matching the cubic-bezier(x1, y1, x2, y2) CSS syntax.

Transition

Describes how a single animated value should move from its current value to a new target: how long it takes, how long to wait before starting, and the easing curve applied over that duration.

TransitionOverrides

Per-group transition overrides layered on top of a base Transition. Each field takes priority over the general transition for its own property group, so e.g. colors and transforms can animate with different durations/easings while sharing one base transition.

TransitionProperty

Which groups of style properties Style::transition should animate.

Enums

Easing

A named or custom timing function used to shape how progress [0.0, 1.0] maps to eased progress over the course of a crate::Transition.
