Struct TransitionManager 

pub struct TransitionManager { /* private fields */ }

Transition manager for handling multiple active transitions

Implementations

impl TransitionManager

pub fn new() -> Self

Create a new transition manager

pub fn start( &mut self, property: impl Into<String>, from: f32, to: f32, transition: &Transition, )

Start a transition for a property

If reduced motion is preferred, the transition completes instantly (no animation, just jumps to final value).

pub fn update(&mut self, delta: Duration)

Update all transitions

pub fn get(&self, property: &str) -> Option<f32>

Get current value for a property

pub fn has_active(&self) -> bool

Check if there are active transitions

pub fn active_properties(&self) -> impl Iterator<Item = &str>

Get all active transition property names

pub fn clear(&mut self)

Clear all transitions

pub fn current_values(&self) -> HashMap<String, f32>

Get all current transition values as a map

Returns a HashMap that can be passed to RenderContext for widgets to access animated property values during rendering.

pub fn start_for_node( &mut self, element_id: impl Into<String>, property: impl Into<String>, from: f32, to: f32, transition: &Transition, )

Start a transition for a specific element

Associates the transition with an element ID for partial rendering. If reduced motion is preferred, no transition is added.

pub fn update_nodes(&mut self, delta: Duration)

Update all node-aware transitions

pub fn get_for_node(&self, element_id: &str, property: &str) -> Option<f32>

Get current value for a property on a specific node

pub fn active_node_ids(&self) -> impl Iterator<Item = &str>

Get all element IDs with active transitions

Used for partial rendering - only these nodes need to be redrawn.

pub fn node_has_active(&self, element_id: &str) -> bool

Check if a specific node has active transitions

pub fn current_values_for_node(&self, element_id: &str) -> HashMap<String, f32>

Get all current transition values for a specific node

Trait Implementations

impl Clone for TransitionManager

fn clone(&self) -> TransitionManager

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TransitionManager

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TransitionManager

fn default() -> TransitionManager

Returns the “default value” for a type.
