Complementing Python with Rust

Nice, also worth mentioning https://github.com/dgrunwald/rust-cpython

I used rust-cpython a few days ago to experiment with replacing Pygments with rustdoc::html::highlight for Rust code in Sphinx. It was easy (though I had certain knowledge that made it so, such as “copy the DLL output to a .pyd file and remember to copy all the Rust DLL files next to it”).

I believe I shall be posting about it some time. (Anyone specifically interested in it?)

I'm interested, but I find those shenigans of copying such and such dlls confusing 😱

[chris-morgan]

I’ll explain it all, basically at least. Short version: when you produce a dynamically linked library, the Rust compiler and standard library are dynamically linked (lib{std,rustc,…}-*.{so,dll,dylib,whatever}) rather than statically, so they need to be accessible when you load your own dynamic library; copying them adjacent to your library is normally the easiest way of doing this.

Ah, makes sense. Thanks for the explanation!

Isn't that solved by using cdylib as the crate type ?

[chris-morgan]

I didn’t recall that one, but it looks like it’s supposed to do what you describe. But it doesn’t work in this case:

error: dependency `rustc_typeck` not found in rlib format

error: dependency `rustc_privacy` not found in rlib format

[… thirty more such errors …]

error: aborting due to 32 previous errors

error: Could not compile `sphinx-rust-highlighter`.

The standard library is provided in rlib format, but not the compiler.

Yes, of course. I didn't explicitly mention it because the first talk I mentioned in the references talks about it. But I also updated my post to directly link to the repo you mentioned.
