Struct RawEntryBuilder

pub struct RawEntryBuilder<'a, K, V, S> { /* private fields */ }

A builder for computing where in an IndexMap a key-value pair would be stored.

This struct is created by the IndexMap::raw_entry_v1 method, provided by the RawEntryApiV1 trait. See its documentation for more.

Implementations

impl<'a, K, V, S> RawEntryBuilder<'a, K, V, S>

fn from_key<Q>(self, key: &Q) -> Option<(&'a K, &'a V)>
where
    S: BuildHasher,
    Q: ?Sized + Hash + Equivalent<K>,

Access an entry by key.

fn from_key_hashed_nocheck<Q>(self, hash: u64, key: &Q) -> Option<(&'a K, &'a V)>
where
    Q: ?Sized + Equivalent<K>,

Access an entry by a key and its hash.

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

Access an entry by hash.

fn from_hash_full<F>(self, hash: u64, is_match: F) -> Option<(usize, &'a K, &'a V)>
where
    F: FnMut(&K) -> bool,

Access an entry by hash, including its index.

fn index_from_hash<F>(self, hash: u64, is_match: F) -> Option<usize>
where
    F: FnMut(&K) -> bool,
