When the program cannot find the
$XDG_CACHE_HOME
directory in the filesystem, it previously panicked. To address this issue, I've added a fallback mechanism to use$HOME/.cache/Iconic
when$XDG_CACHE_HOME
is not set.Default path for
$XDG_CACHE_HOME
is specified by the Freedesktop-basedir specification: https://specifications.freedesktop.org/basedir-spec/latest/Also I've formatted rust sources using cargo fmt
