Type Alias rustc_data_structures::fx::FxHashMap

pub type FxHashMap<K, V> = HashMap<K, V, BuildHasherDefault<FxHasher>>;

Type alias for a hashmap using the fx hash algorithm.

Aliased Type

struct FxHashMap<K, V> {
    base: HashMap<K, V, BuildHasherDefault<FxHasher>, Global>,
}

Fields

base: HashMap<K, V, BuildHasherDefault<FxHasher>, Global>

Trait Implementations

impl<K: Eq + Hash, V: Eq, S: BuildHasher> HashMapExt<K, V> for HashMap<K, V, S>

fn insert_same(&mut self, key: K, value: V)

Same as HashMap::insert, but it may panic if there’s already an entry for key with a value not equal to value

impl<K, V, R, HCX> HashStable<HCX> for HashMap<K, V, R>where K: ToStableHashKey<HCX> + Eq, V: HashStable<HCX>, R: BuildHasher,

fn hash_stable(&self, hcx: &mut HCX, hasher: &mut StableHasher)

impl<K, V> Rollback<UndoLog<K, V>> for FxHashMap<K, V>where K: Eq + Hash,

fn reverse(&mut self, undo: UndoLog<K, V>)

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.
