Add "rust-version" field in Cargo.toml (when stable)

[GuillaumeGomez]

The RFC for this feature is there and the documentation is there.

Update: This has become stable with Rust 1.56 but sysinfo minimum rust-version at this time is 1.54 so still not possible.

Wanna send a PR to fix it? :)

I'm waiting for a libc PR to be merged before making the next release in any case but that would still be one less thing to worry about.

[poliorcetics]

I'm okay with doing a PR but it means updating the MSRV, do you want to do this ?

[GuillaumeGomez]

It isn't an issue. Unknown fields don't prevent cargo to work and don't emit warnings either, they're just ignored. No need to update the MSRV.

[poliorcetics]

The doc linked says rust-version will produce a warning when present but on less than 1.56

The first version of Cargo that supports this field was released with Rust 1.56.0. In older releases, the field will be ignored, and Cargo will display a warning.

I can't test right now, will do when getting home

👍

This has been done and can be closed, sorry I didn't come back to you when I said I would

Fixed in #605.
