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>

pub 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.

pub 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.

pub 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.

pub 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.

pub fn index_from_hash<F>(self, hash: u64, is_match: F) -> Option<usize>

where F: FnMut(&K) -> bool,

Access the index of an entry by hash.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
