pub fn scan(root: &Path) -> Result<Vec<Session>>Expand description
Every session under root, open or left behind.
A directory carrying no readable record is skipped rather than reported: it is a session being created by another process right now, or the remains of one that died between the two operations, and neither is something to fail a recovery scan over.
ยงErrors
Where root exists and cannot be read. A root that is not there yet is an
empty list, because a machine that has never opened a container has no
sessions rather than a problem.
