Implementations

impl<'a> StyleCx<'a>

pub fn new( window_state: &'a mut WindowState, view_id: ViewId, reason: StyleReason, ) -> Self

pub fn style_view(&mut self)

Compute styles for a view with graduated change propagation.

The change parameter describes what kind of recalculation is needed, enabling optimizations like:

• Skipping views that don’t need recalc
• Using the inherited-only fast path when only inherited props changed
• Limiting recalc to immediate children vs entire subtrees

See [StyleRecalcChange] for details on the propagation model.

pub fn resolve_nested_maps( &self, base_style: Style, classes: &[StyleClassRef], element_id: impl Into<ElementId>, ) -> Style

Resolve all nested maps in the base style for the given classes. This will use the current style cx as context and get the interaction state for the given element

pub fn resolve_nested_maps_with_state( &self, base_style: Style, classes: &[StyleClassRef], interact_state: InteractionState, ) -> Style

The base style the base style for this view that will override any inherited properties

pub fn now(&self) -> Instant

pub fn current_view(&self) -> ViewId

pub fn get_prop<P: StyleProp>(&self, _prop: P) -> Option<P::Type>

pub fn style(&self) -> Style

pub fn direct_style(&self) -> &Style

pub fn indirect_style(&self) -> &Style

pub fn request_transition(&mut self)

pub fn request_transition_for(&mut self, target: impl Into<ElementId>)

Request a transition-driven style update for a specific style target.

This allows transition requests to target sub-elements instead of always assuming the owning view element.

pub fn get_interact_state( window_state: &WindowState, id: impl Into<ElementId>, ) -> InteractionState
