Relation between maturin and cross-rs?

[bluenote10]

I'm new to the cross compiling world, and I'm frequently seeing recommendations to use cross.

I'm generally trying to understand what is the relationship between maturin and cross. Does maturin already use cross internally in one way or another? If not, would it make sense to somehow use them together, i.e., could maturin delegate compilation to cross for easier cross compilation?

Motivation: Whenever I'm encountering a situation that involves third party dependencies outside the manylinux scope (libasound2, libdbus, ...) I'm basically hitting a wall with cross compilation using maturin. So I was wondering if things would get easier with cross seeing e.g. this example.

No.

You can try set CARGO=cross but it's not well tested and may not work at all.
