Struct halfbrown::RawEntryBuilder

pub struct RawEntryBuilder<'map, K, V, S>(_);

A builder for computing where in a [HashMap] a key-value pair would be stored.

See the HashMap::raw_entry docs for usage examples.

Implementations

impl<'map, K, V, S> RawEntryBuilder<'map, K, V, S>where
    S: BuildHasher,

pub fn from_key<Q>(self, k: &Q) -> Option<(&'map K, &'map V)>where
    K: Borrow<Q>,
    Q: Hash + Eq + ?Sized,

Access an entry by key.

pub fn from_key_hashed_nocheck<Q>(
    self,
    hash: u64,
    k: &Q
) -> Option<(&'map K, &'map V)>where
    K: Borrow<Q>,
    Q: Hash + Eq + ?Sized,

Access an entry by a key and its hash.

pub fn from_hash<F>(self, hash: u64, is_match: F) -> Option<(&'map K, &'map V)>where
    F: FnMut(&K) -> bool,

Access an entry by hash.
