It offers additional algorithms and functionality on top of the core data structures offered in the petgraph library. This crate contains the Rust library rustworkx-core. This library is part of the rustworkx project. However while the larger rustworkx project is a Python library that offers a general purpose high performance graph library written in Rust, rustworkx-core is a pure rust library that offers a stable rust API for any downstream crate that need it. At it's core rustworkx is built on top of the [petgraph](https://github.com/petgraph/petgraph) library and wraps it in a Python layer. However, many of the algorithms (and to a lesser extent data structures) needed for rustworkx are not available in petgraph. For places where these algorithms are implemented in a generic way the rustworkx-core crate exposes it for Rust users. ## Usage Add this to your `Cargo.toml`: ```toml [dependencies] rustworkx-core = "0.11" ``` Then: ```rust use rustworkx_core; ``` Note there is a strong version dependency between `petgraph` and `rustworkx-core` as the functionality exposed by rustworkx-core is built on top of petgraph. For convenience we re-export `petgraph` in the root of this crate so you can use petgraph without explicitly needing it at the same exact version in your crate. ## License Just as with the rest of the rustworkx project rustworkx-core is licensed under the Apache License, Version 2.0: https://www.apache.org/licenses/LICENSE-2.0
