Struct MotionAnchor 

Source 
pub struct MotionAnchor(/* private fields */);
Expand description

Retained measurement of one native element in logical window coordinates. Mount each anchor once. Clones share storage. clear releases a stale measurement before reusing the owner in another window.

Implementations§

Source§

impl MotionAnchor

Source

pub fn scroll_source(self, handle: ScrollHandle) -> Self

Tracks current native offsets between measurements, preventing a frame of scroll lag. Use the target’s nearest scrolling ancestor.

Source

pub fn rect(&self) -> Option<LayoutRect>

Last measured rectangle, adjusted for an explicitly tracked scroll source.

Source

pub fn clear(&self)

Releases identity/measurement history; does not keep a native element alive.

Source

pub fn element<E: IntoElement + 'static>( &self, id: impl Into<ElementId>, child: E, ) -> AnchorElement<E>

Measures an ordinary child, retaining its input and accessibility semantics.
