Updating hiem with older transitive dependency on nix

[froismo]

I'm new to rust, so maybe I'm mistaken, and if so, sorry for wasting your time.

Vector depends on nix version 0.26.1, and a Vector-supported version of heim depends on ^0.23.0. When vector is built will the heim module have its own version of nix, or will it use the nix from the enclosing project?

Specifically, I'm hoping to get nix updated to remediate nix-rust/nix#1762 which is in nix versions above 0.25.0.

Hi @froismo !

(converted the issue you opened to a discussion since I think that fits better)

Vector depends on several versions of nix:

You can use cargo tree -i -p nix@some_version to see the inverted dependency tree. As you note, heim depends on 0.23:

Heim will need to be forked and updated to resolve that.

Well, I see we are already forking it, so you could just open a PR to https://github.com/vectordotdev/heim 😄

I'll give it a go, thank you.

I had hoped this was a matter of dependabot not running on vector's heim repo, and just needing a little tickle. It's more than that, and I'm not proficient in rust. I agree with your assessment heim-rs looks a little dead.
