Mixing up toolchain versions?

[matthiasgoergens]

Our rust-toolchain specifies nightly-2024-05-02. That one comes with rustfmt version 1.7. But our rustfmt.toml uses style_edition = "2024"; but 2024 was only added in version 1.8.

Is this mix-up intentional?

There are multiple ways to fix this: update the nightly that we are using, or change what options we specify. Or: just ignore the issues altogether.

Updating the nightly is presumably something we want to do eventually anyway, but it also comes with wider consequences.

Just to be clear: this is a very low priority issue. I'm just going through configuration and warnings as part of my ritual to explore a new code base. So feel free to ignore this.
