Per the commit f26137893b98 ("rust: remove unnecessary Cargo.toml
metadata"), readme & repository are not necessary. :-)

And rust-version is needed (since the commit 669fab6a1f3e).

I think it's necessary add the lints section to apply workspace's lint
configurations:

[lints]
workspace = true

And doc can be updated in docs/devel/rust.rst, like Paolo's patch:

I'm unsure without testing, the dependencies here looks different with
the Cargo.toml?
