pub fn router_root(root_dest: impl RouterDestination + 'static)Expand description
Root component that drives the shard router stack each frame.
See module‑level docs for detailed usage patterns.
§Parameters
root_dest- The destination pushed only once when the stack is empty.
§Notes
Keep router_root exactly once at the point in your tree that should display
the active routed component. Wrapping it multiple times would still execute
only one top destination but wastes layout work.
