Struct scc::hash_map::Ticket

source · [−]

pub struct Ticket<'h, K, V, H> where
    K: 'static + Eq + Hash + Sync,
    V: 'static + Sync,
    H: BuildHasher,  { /* private fields */ }

Expand description

Ticket keeps the increased minimum capacity of the HashMap during its lifetime.

The minimum capacity is lowered when the Ticket is dropped, thereby allowing unused memory to be reclaimed.
