Struct SharedLayout 

pub struct SharedLayout<K>(/* private fields */);

View-owned shared identity registry. Exactly one active destination per key is required. Render incoming/outgoing appearances in a common overlay; retain outgoing content until its normal presence exit completes. Native clipping still applies, sizes change immediately, and independent scrolling coordinate spaces are not reconciled. This is position/crossfade, not full layoutId. Clones share storage. Call remove when a logical shared identity is finished.

Implementations

impl<K: Eq + Hash + Clone + 'static> SharedLayout<K>

pub fn remove(&self, key: &K)

Forgets a shared identity. Existing native member history ends on unmount.

pub fn len(&self) -> usize

Number of explicitly retained shared identities.

pub fn is_empty(&self) -> bool

Whether no identities are retained.

pub fn member<E: IntoElement + Styled + 'static>( &self, key: K, id: impl Into<ElementId>, active: bool, child: E, ) -> SharedElement<K, E>

Creates a crossfading appearance. Styles and absolute positioning belong on the child. Inactive retained appearances follow the active position. The owner must suppress input and restore focus for outgoing appearances, just as with normal presence exits; opacity does not disable handlers.

use gpui_kit::{div, prelude::*, px};
use gpui_motion_kit::SharedLayout;
let shared = SharedLayout::<u32>::default(); // persistent view field
let first = shared.member(1, "old", false, div().absolute().left(px(0.)).child("Old"));
let second = shared.member(1, "new", true, div().absolute().left(px(200.)).child("New"));
let overlay = div().relative().child(first).child(second);
