HELP: how to configure Conda-Forge Feedstock for Rust/Python Mixed Projects?

[attack68]

I currently have no idea how to configure Conda to cross-compile and build this project in Conda Forge.

Anyone with knowledge, please contact me:

I've no experience of this myself, but I note from the conda discourse thread you were looking at pydantic as a sample. The pydantic package itself is pure python, the Rust extension is pydantic-core on which it depends.

The meta file for that is here:
https://github.com/conda-forge/pydantic-core-feedstock/blob/main/recipe/meta.yaml

Note in particular how compilers have been added as required build dependencies.

Another package I've seen sited as a Rust example in another context is cryptography. It looks like it has a similar set-up:
https://github.com/conda-forge/cryptography-feedstock/blob/main/recipe/meta.yaml#L52

Hope this might prove of some help.

Thanks @NickAltmann I will take a look at this and see if I can piece something together from it.
