.
Implementations§
source§impl<'h, K, V, H> VacantEntry<'h, K, V, H>where
K: 'static + Clone + Eq + Hash,
V: 'static + Clone,
H: BuildHasher,
impl<'h, K, V, H> VacantEntry<'h, K, V, H>where K: 'static + Clone + Eq + Hash, V: 'static + Clone, H: BuildHasher,
sourcepub fn key(&self) -> &K
pub fn key(&self) -> &K
Gets a reference to the key.
Examples
use scc::HashIndex;
let hashindex: HashIndex<u64, u32> = HashIndex::default();
assert_eq!(hashindex.entry(11).key(), &11);
sourcepub fn into_key(self) -> K
pub fn into_key(self) -> K
Takes ownership of the key.
Examples
use scc::HashIndex;
use scc::hash_index::Entry;
let hashindex: HashIndex<u64, u32> = HashIndex::default();
if let Entry::Vacant(v) = hashindex.entry(17) {
assert_eq!(v.into_key(), 17);
};
sourcepub fn insert_entry(self, val: V) -> OccupiedEntry<'h, K, V, H>
pub fn insert_entry(self, val: V) -> OccupiedEntry<'h, K, V, H>
Sets the value of the entry with its key, and returns an OccupiedEntry
.
Examples
use scc::HashIndex;
use scc::hash_index::Entry;
let hashindex: HashIndex<u64, u32> = HashIndex::default();
if let Entry::Vacant(o) = hashindex.entry(19) {
o.insert_entry(29);
}
assert_eq!(hashindex.read(&19, |_, v| *v), Some(29));
