[−][src]Struct std::collections::hash_map::RawEntryBuilder
A builder for computing where in a HashMap a key-value pair would be stored.
See the HashMap::raw_entry
docs for usage examples.
Methods
impl<'a, K, V, S> RawEntryBuilder<'a, K, V, S> where
S: BuildHasher,
[src]
S: BuildHasher,
pub fn from_key<Q: ?Sized>(self, k: &Q) -> Option<(&'a K, &'a V)> where
K: Borrow<Q>,
Q: Hash + Eq,
[src]
K: Borrow<Q>,
Q: Hash + Eq,
Access an entry by key.
pub fn from_key_hashed_nocheck<Q: ?Sized>(
self,
hash: u64,
k: &Q
) -> Option<(&'a K, &'a V)> where
K: Borrow<Q>,
Q: Hash + Eq,
[src]
self,
hash: u64,
k: &Q
) -> Option<(&'a K, &'a V)> where
K: Borrow<Q>,
Q: Hash + Eq,
Access an entry by a key and its hash.
pub fn from_hash<F>(self, hash: u64, is_match: F) -> Option<(&'a K, &'a V)> where
F: FnMut(&K) -> bool,
[src]
F: FnMut(&K) -> bool,
Access an entry by hash.
pub fn search_bucket<F>(self, hash: u64, is_match: F) -> Option<(&'a K, &'a V)> where
F: FnMut(&K) -> bool,
[src]
F: FnMut(&K) -> bool,
Search possible locations for an element with hash hash
until is_match
returns true for
one of them. There is no guarantee that all keys passed to is_match
will have the provided
hash.
