Struct WeakStore 

pub struct WeakStore { /* private fields */ }

Weak handle to a Store — does not keep the underlying keyspace alive.

Used by the URL-keyed registry in kevy-client so that multiple Connection::connect("mem://name") calls share the same backing store without leaking it when all strong handles go away.

let s = kevy_embedded::Store::open(kevy_embedded::Config::default())?;
s.set(b"k", b"v")?;
let weak = s.downgrade();
let again = weak.upgrade().ok_or("the store is still alive")?;
assert_eq!(again.get(b"k")?.as_deref(), Some(&b"v"[..]), "same keyspace");
drop((s, again));
assert!(weak.upgrade().is_none(), "the last strong handle is gone");
