I wrote this as an example, but it sounds like you already know how to do that.

> Introduction I was asked for a simple example about how to call Rust from Julia on Slack. I thought I would post it here for posterity. Just to emphasize, my goal here is simplicity. For practical use, you would probably want to use cargo with [jlrs](https://discourse.julialang.org/t/jlrs-v0-19-many-performance-optimizations/102253). That said, I do find some virtue in simple and reductionist demonstrations. The code hellojulia.rs: #[no\_mangle] pub extern "C" fn rust\_add(a: i64, b: i64) -\> i64 { return 2\*a + 3\*b } hellorust.jl const libpath = "./libhellojulia.so" hellor…

If there were some additional support, I think it would end up looking more like CxxWrap.jl.

The existence of `cargo` does seem like a significant difference though, so perhaps a Julia wrapper of some sort would make sense similar to Conda.jl.

For a Julia package though, you probably would just want to use BinaryBuilder.jl to build the the C FFI.
