Show HN: HypergraphZ – A Hypergraph Implementation in Zig

HypergraphZ is a directed hypergraph implementation developed in the Zig programming language, enabling users to create hypergraphs where hyperedges can contain zero, one, or multiple vertices, and can include vertices directed to themselves multiple times. To integrate HypergraphZ into a project, users must add it as a dependency in their `build.zig.zon` file using a specific command to fetch the repository. After fetching, it should be included in the `build.zig` file to ensure proper functionality. The project also provides online documentation for users seeking further information or assistance regarding its usage.

- HypergraphZ is implemented in the Zig programming language.

- It supports hyperedges with multiple vertices, including self-directed vertices.

- Users can add HypergraphZ as a dependency via a command in the `build.zig.zon` file.

- Documentation for HypergraphZ is available online for user reference.

- The project encourages users to ask questions for more specific information.

I see that this is a second implementation, the first being in Rust: https://github.com/yamafaktory/hypergraph

I've found that Zig is an excellent tool for implementing data-structure-oriented libraries. Comptime genericity is simple to understand and use, providing a C interface is very easy, and libraries take an allocator, so any memory-safety issues are the consumer's problem. If you want to use it from a memory-safe language, well, all of those have C FFIs so far as I know, Rust very much included, so you can.

A hypergraph is clearly a data structure which demands a lot of cyclic references, no getting around that, so I'm curious: can you compare and contrast the experience of implementing this in Rust vs. Zig?

How does this compare to a relational database, where hyperedges are represented by tables and vertices by values?

Really cool! I would be interested in seeing a hypergraph isomorphism algorithm implemented in Zig.

I don't know why, but I feel Zigergraph would be a meaningful name :)

Do you think this can be useful for a computational algebra system?
