pub fn default_user_config_path() -> Option<PathBuf>Expand description
Default user config path: <config_home>/lattice/lattice.toml, i.e.
~/.config/lattice/lattice.toml (honouring $XDG_CONFIG_HOME). See
config_home for the cross-platform resolution. None when no config
home resolves (no $XDG_CONFIG_HOME override and no $HOME).
