hugr-persistent

The Hierarchical Unified Graph Representation (HUGR, pronounced hugger) is the common representation of quantum circuits and operations in the Quantinuum ecosystem.

It provides a high-fidelity representation of operations, that facilitates compilation and encodes runnable programs.

The HUGR specification is here.

Overview

This crate provides a persistent data structure for HUGR mutations; mutations to the data are stored persistently as a set of Commits along with the dependencies between them.

As a result of persistency, the entire mutation history of a HUGR can be traversed and references to previous versions of the data remain valid even as the HUGR graph is "mutated" by applying patches: the patches are in effect added to the history as new commits.

Usage

Add the dependency to your project:

cargo add hugr-persistent
