[−][src]Struct arc_swap::gen_lock::PrivateUnsharded
A single „shard“ that is stored inline, inside the corresponding ArcSwap
. Therefore, locks on
each instance won't influence any other instances. On the other hand, the ArcSwap
itself gets
bigger and doesn't have multiple shards, so concurrent peek
s (or fallbacks on lease
) might
contend each other a bit.
// This one shares locks with others. let shared = ArcSwap::from_pointee(42); // But this one has an independent lock. let independent = ArcSwapAny::<Arc<usize>, PrivateUnsharded>::from_pointee(42); // This'll hold a lock so any writers there wouldn't complete let l = independent.peek(); // But the lock doesn't influence the shared one, so this goes through just fine shared.store(Arc::new(43)); assert_eq!(42, *l);
Note that theres a type alias [
IndependentArcSwap`](../type.IndependentArcSwap.html) that can
be used instead.
