rsdiff

---

Warning: The library is currently in the early stages of development and is not yet ready for production use.

rsdiff is a Rust library enabling the automatic differentiation of functions using various techniques

Background

Autodifferentiation is a powerful technique used in machine learning and optimization, allowing for efficient computation of gradients. The rsdiff library aims to provide a robust foundation for building autodifferentiation systems by leveraging hypergraphs to represent complex relationships between variables.

Features

• hash_graph - A hash-based hypergraph implementation.

Usage

Add this to your Cargo.toml:

[dependencies.rsdiff]
features = [
    "hash_graph",
    "macros",
]
version = "0.1.x"

Examples

For more detailed examples, please refer to the examples directory.

Example #1: Basic Usage

    extern crate rsdiff;

    fn main() -> rsdiff::Result<()> {
        // initialize a new instance of a hypergraph
        let mut graph: HashGraph<usize, usize> = HashGraph::new();
        // use the macro to insert nodes into the graph
        rsdiff::hypernode! {
            graph {
                let v0;
                let v1 = 2;
                let v2 = 3;
                let v3 = 4;
            }
        }
        // Add some hyperedges
        let e1 = graph.insert_edge(vec![v0, v1, v2])?;
        println!("Added hyperedge {e1}: {:?}", [v0, v1, v2]);

        let e2 = graph.insert_edge(vec![v1, v2, v3])?;
        println!("Added hyperedge {e2}: {:?}", [v1, v2, v3]);

        // Get neighbors of vertex v1
        let neighbors = graph.neighbors(&v1)?;
        println!("Neighbors of {}: {:?}", v1, neighbors);

        // Get degree of vertex v1
        let degree = graph.get_degree_of_node(&v1);
        println!("Degree of {v1}: {degree}");

        // Remove a vertex
        graph.remove_vertex(&v2)?;
        println!("Removed vertex {v2}");

        println!("---------\nFinal graph state: {:?}", graph);
        Ok(())
    }

Getting Started

Prerequisites

Ensure you have the latest version of Rust installed. You can install Rust using rustup.

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

After installation, I always recommend ensuring that rustup is updated to the latest version:

rustup update

And to add the latest nightly toolchain, which is often useful for development:

rustup toolchain install nightly

Additionally, you may wish to install the cargo-binstall utility to streamline the installation of Rust binaries:

cargo install cargo-binstall

If necessary, add the wasm32-* target(s) if you plan to compile for WebAssembly:

rustup target add wasm32-unknown-unknown wasm32-p1 wasm32-p2

Building from the source

Start by cloning the repository

git clone https://github.com/FL03/rsdiff.git -b main --depth 1

Then, navigate to the project directory:

cd rsdiff

Once you're in the project directory, you can build the project using cargo:

cargo build --workspace --release --all-features

Or, if you want to run the tests, you can use:

cargo test --workspace --release --all-features
