Enum DockLayoutApply 

pub enum DockLayoutApply {
    IfMissing,
    Replace,
}

Policy controlling whether an existing persisted dock tree is preserved.

Variants

IfMissing

Build only when the root did not exist before this frame’s dockspace submission.

Replace

Replace the existing root with the complete declared layout.

The topology is staged under a temporary root before the native commit point. Validation and recoverable staging failures leave an existing layout unchanged and alive for the current frame. A successful replacement preserves the root ID, but child-node IDs, tab selection, focus, and relative tab order are not stable across replacement. Replacement must be submitted before any affected window begins its frame.
