Struct TransitionScope 

pub struct TransitionScope<T> { /* private fields */ }

A scope for multi-target animations driven by a changing state.

When the target state changes (detected via PartialEq), all child animations registered via animate_float, animate_color, etc. automatically animate from their current value toward the new mapped target value.

Example

let t = update_transition("panel", is_expanded, AnimationSpec::spring_gentle());
let h  = t.animate_float("height", |e| if *e { 200.0 } else { 48.0 });
let bg = t.animate_color("bg", |e| if *e { theme().primary } else { theme().surface });
