Cargo check fails in github CI

[atanmarko]

By enabling cargo-check.enable = true in default.nix, following error happens:

cargo-check..............................................................Failed

- hook id: cargo-check
- exit code: 101

Caused by:

Is this an issue specific to the base-x dependency, or something more subtle regarding Nix (question for @Anderssorby)?

If the former, it might be worth looking into alternatives to https://github.com/OrKoN/base-x-rs

[Anderssorby]

I'll take a look at it.

Opened an issue: cachix/git-hooks.nix#94

[Anderssorby]

So to clarify this is an issue with nix disallowing internet access which cargo check uses. To avoid this the cargo cache needs to be loaded beforehand like in naersk. So a fix would be to add cargo check support to naersk nix-community/naersk#163

I think this should be closed, as GitHub CI checks passsed for #19 and #20
