right, the binary package is not called rust-bat but the source package is [1].
Can lintian check for the source package name? (also not sure if it is
a good idea).
Do you think it would be a good idea to rename the binary package?
Or maybe we could try find another string that is present in libyaml and not
in rust-yaml-rust.

Just a question regarding how lintian works: one thing that confused me is that
bat doesn't depend on rust-yaml-rust directly, it depends on rust-syntect which
depends on rust-yaml-rust. So I was wondering why I didn't get this
error in lintian
when building rust-syntect.
