Enum LeafRemoval 

pub enum LeafRemoval {
    Removed,
    WasRoot,
    NotFound,
}

Outcome of LayoutNode::remove_leaf. Removing a pane either collapses its parent split into the surviving sibling, removes the only pane (leaving nothing the tree can represent — the caller must close the window), or finds no such pane.

Variants

Removed

The leaf was removed and its parent split collapsed into the sibling subtree. The tree still holds ≥1 pane.

WasRoot

The leaf was the root — the tree is a single pane and cannot represent emptiness. The caller closes the window/pane instead.

NotFound

No leaf with that id exists in the tree.
