1. git clone https://github.com/snapcraft-docs/xsv.git
2. cd xsv
3. sed -i 's/base:.*/base: core22/' snapcraft.yaml
4. snapcraft

Adding a `after: [rust-deps]` doesn't help:

is the dependency of providing cargo satisfied by the rust-deps part? Perhaps that is what needs to be made clearer.

[Michał Sawicz (saviq)]

If that's the case, shouldn't the plugin handle it?

https://snapcraft.io/docs/rust-plugin#heading--core22 does not mention `rust-deps`.

[Michał Sawicz (saviq)]

FWIW this is still the case.

[Zixing Liu (liushuyu-011)]

This seems to be an issue with `craft-parts` (and the Rust plugin) having the `cargo` check before installing it.
I am unsure who to contact to correct this logic.

Hi there,

I have opened a pull request on GitHub to address this issue: https://github.com/snapcore/snapcraft/pull/4297.
