§dcel

Dynamic doubly-connected edge list (DCEL) in Rust.

A DCEL is a topological data structure that represents an embedding of a planar graph in the plane. DCEL partitions a surface into easily and quickly traversable vertices, edges, and faces, while making only minimal assumptions about their shapes. You can freely choose wherever the vertices should have two or more dimensions, or wheverer the edges are line segments or curved arcs.

In mathematics, particularly in topological graph theory and algebraic graph theory, planar graph embeddings in the plane are represented using concepts such as cellularly embedded graph, ribbon graph, band decomposition, ram graph, arrow presentation, signed rotation system.
