Boost 1.75.0 polygon::voronoi ported to 100% rust. This implementaton of Forune's algorithm works on line segments as well as points, making it useful for finding centerlines or whatnot.
Quick example:
set -x LIBRARY_PATH /opt/local/lib/ #or whatever you store your SDL
cargo run --example piston_gui
