The current ebuild of gui-app/eww-0.4.0 depends on dev-lang/rust. Could you make it depend on dev-lang/rust-bin or dev-lang/rust? I run gentoo on an old laptop and would like to prevent an emerge of dev-lang/rust if possible.
Unfortunately this package cannot be built with dev-lang/rust-bin.
Which version of rust does gui-apps/eww-0.4.0 use? I have stable dev-lang/rust-1.69.0-r1 installed but the emerge of eww failed with it. If this requires another bug report I'll file one later. Or if an upgrade to a correct version solves the problem I'll just do it.
