compile arror

[daktras420]

from what i understand the maintainer of the aur build of gross is not the same maintainer as the original author so i am not sure whom to direct this issue too..but when compiling i get the following....

paru -S gross :: Resolving dependencies... :: Calculating conflicts... :: Calculating inner conflicts...

when i run rustc --explain E0635 i get the following The #![feature] attribute specified an unknown feature.

Erroneous code example:

not sure how to fix this please help thanks in advance

Have you tried compiling with rustup ? I installed the aur package just a few days ago (plain arch linux) and changed to rustup due to deps of a package. Not sure if it helps tho.

Yes i am using rustup and went through the whole arch install process to setup rustup and successful installed eww using the package from aur eww-tray-wayland-git. Despite all this as you can see it's not compiling.
