fn parent(&self, node: impl AsRef<NodeID>) -> Result<Option<NodeID>>

fn children(&self, node: Option<impl AsRef<NodeID>>) -> Result<Nodes>

fn has_children(&self, node: impl AsRef<NodeID>) -> Result<bool>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
