[][src]Struct std::collections::hash_map::RawEntryBuilder

pub struct RawEntryBuilder<'a, K: 'a, V: 'a, S: 'a> { /* fields omitted */ }
🔬 This is a nightly-only experimental API. (hash_raw_entry #56167)

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]

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

🔬 This is a nightly-only experimental API. (hash_raw_entry #56167)

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]

🔬 This is a nightly-only experimental API. (hash_raw_entry #56167)

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]

🔬 This is a nightly-only experimental API. (hash_raw_entry #56167)

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]

🔬 This is a nightly-only experimental API. (hash_raw_entry #56167)

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.
