Struct std::collections::hash_map::RawEntryBuilderMut

pub struct RawEntryBuilderMut<'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_mut docs for usage examples.

Methods

impl<'a, K, V, S> RawEntryBuilderMut<'a, K, V, S> where
    S: BuildHasher,
    K: Eq + Hash, 

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

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

Creates a RawEntryMut from the given key.

pub fn from_key_hashed_nocheck<Q: ?Sized>(
    self,
    hash: u64,
    k: &Q
) -> RawEntryMut<'a, K, V, S> where
    K: Borrow<Q>,
    Q: Eq, 

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

Creates a RawEntryMut from the given key and its hash.

pub fn from_hash<F>(self, hash: u64, is_match: F) -> RawEntryMut<'a, K, V, S> where
    F: FnMut(&'b K) -> bool, 

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

Creates a RawEntryMut from the given hash.

pub fn search_bucket<F>(
    self,
    hash: u64,
    is_match: F
) -> RawEntryMut<'a, K, V, S> where
    F: FnMut(&'b K) -> bool, 

🔬 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.
