Struct LOTable 

Source 
pub struct LOTable<K, V, S = RandomState>
where
    K: 'static + PartialEq + Eq + Hash + Clone + Send + Sync,
    V: 'static + Clone + Send + Sync,
    S: BuildHasher,

Expand description

Lever Transactional Table implementation with Optimistic concurrency and RepeatableRead isolation.

Transactional hash table fully concurrent and as long as no conflicts are made it is both lock and wait free.
