pub fn adc_path(env: &Environment<'_>) -> Option<PathBuf>Expand description
The application default credentials file, where object_store reads it:
%APPDATA%\gcloud\ on Windows, $HOME/.config/gcloud/ elsewhere. Kept in step with
object_store::gcp deliberately: discovery must agree with the code that will later
do the opening, and looking under the home directory on Windows found nothing.
