async fn local_base_tracks_upstream(
cwd: &Path,
base: &str,
deadline: Option<Instant>,
) -> Option<bool>Expand description
Whether the local base itself tracks a remote (main@{upstream}): a base
that does can be behind that remote exactly as an origin/... can, and
nothing was fetched for it here. None when git could not answer, which
the caller treats as unverified rather than as “nothing to lag behind”.
