        _path: &ExId,
    ) -> bool { ... }
}

Optional cross-device continuation capability for an app root.

Continuation is deliberately separate from Widget: ordinary controls have no resumable app state, while roots that do can expose this capability through [Widget::continuable] without weakening their UI integration.

Required Methods

fn continuation_metadata( &self, state: &AutoCommit, path: &ExId, ) -> Option<ContinuationMetadata>

Return a compact, path-free projection of state that may be resumed on another device owned by the same person.

fn restore_continuation_metadata( &mut self, metadata: &ContinuationMetadata, state: &mut Edits<'_>, path: &ExId, ) -> bool

Apply a continuation projection after launch. Implementations must not change focus or start media; malformed or unknown metadata is ignored.

Provided Methods

fn restore_live_continuation_metadata( &mut self, _metadata: &ContinuationMetadata, _state: &AutoCommit, _path: &ExId, ) -> bool

Apply a live owner view to an already-bound resource. This opt-in capability receives no writable document and must preserve focus. Missing resources or anchors are refused so the host can defer or cancel the projection when its authenticated source disappears.
