causal-triangulations: A Causal Dynamical Triangulation library for quantum gravity research

Rust crate providing Causal Dynamical Triangulations for quantum gravity research. The library implements validated 1+1 CDT construction, foliation checks, Metropolis-Hastings sampling over causal local moves, Regge action calculation, simulation outputs, checkpoints, and observables including volume profiles, Hausdorff-dimension estimates, and spectral-dimension estimates. It builds on Delaunay triangulation primitives, keeps geometry and CDT domain logic separated, and provides a command-line binary plus focused public APIs for simulation and analysis workflows. Written in safe Rust with no unsafe code.
