jlrs VS DaemonMode.jl

And in the rare case that Julia isn't enough, Julia-Rust interop is pretty good! Julia can call Rust using ccall and Rust can call Julia using the jlrs crate.

While there is Jlrs , there is no seamless and easy way to call Rust. We need 'rustcall' on a level of 'pycall'.

I have a roadmap issue with some ideas/designs/arguments https://github.com/Taaitaaiger/jlrs/issues/66

An option for Julia/Rust interop is jlrs

jlrs automates some of this, using stack frames to garantee that Julia won't gc the references you're holding in Rust. It also provides ways to coerce Rust structs into Julia structs, and it does a bunch of other stuff I'm probably forgetting.

Thats for an entry point, you can search `Base.@main` to see a little summary of it. Later it will be able to be callable with `juliax` and `juliac` i.e. `~juliax test.jl` in shell.

DynamicalSystems looks like a heavy project. I don't think you can do much more on your own. There have been recent features in 1.10 that lets you just use the portion you need (just a weak dependency), and there is precompiletools.jl but these are on your side.

You can also look into https://github.com/dmolina/DaemonMode.jl for running a Julia process in the background and do your stuff in the shell without startup time until the standalone binaries are there.

Because you're compiling...

And if you need to do the same in Julia, you should also pre-compile or some other method like https://github.com/dmolina/DaemonMode.jl (their demo shows loading a database, with subsequent loads after the first one taking roughly ~0.2% of the first)

Well, not nicely certainly, but:

Neither is python - it just relies on universal availability. Over time…

You can get around a lot of these problems with DaemonMode.jl though.

You might want DaemonMode.jl

https://github.com/dmolina/DaemonMode.jl can possibly help in the future. Leaving it here so that people know this is planned.

If you strongly prefer to run scripts though, then you can use the package https://github.com/dmolina/DaemonMode.jl in order to re-use a Julia session between multiple scripts, saving you recompilation time.
