A few months ago I released the first version of jlrs, a crate (library) for the Rust programming language that provides bindings to he Julia C API. I’ve continued working on it and recently version 0.5 has been released. A lot has changed since the earliest version. That version used many indirections to provide basic functionality, and over the releases jlrs has been rewritten in a way that (I think) offers an API that is comfortable to people who are familiar with Rust, expressed in a way that’s close to the Julia C API.

The major features that jlrs currently offers are:  
- Access arbitrary Julia modules and their contents.  
- Call arbitrary Julia functions.  
- Include and use your own Julia code (including support for custom sytem images).  
- Create values that Julia can use, and convert them back to Rust, from Rust.  
- Access the type information and fields of values and check their properties.  
- Support for mapping isbits tuples and structs to Rust structs.  
- Create and use n-dimensional arrays.

Both Windows and Linux are supported, you can find build instructions on [Github](https://github.com/Taaitaaiger/jlrs) and in the [docs](https://docs.rs/jlrs/0.5.0/jlrs/index.html).
