#![warn(missing_docs)]
//! This file implements a labelled graph.  See the trait
//! [`LabelGraph`][crate::LabelGraph] for details.
//!
//! Since the method
//! [`find_children_with_label`][super::LabelGraph::find_children_with_label]
//! needs to be implemented efficiently, we store the mappings between
//! labels and edges in both directions.
