}

Fields

cache: Sharded<FxHashMap<K, (V, DepNodeIndex)>>

Trait Implementations

impl<K, V> Default for DefaultCache<K, V>

fn default() -> Self

Returns the “default value” for a type.

impl<K, V> QueryCache for DefaultCache<K, V>where K: Eq + Hash + Copy + Debug, V: Copy,

type Key = K

type Value = V

fn lookup(&self, key: &K) -> Option<(V, DepNodeIndex)>

Checks if the query is already computed and in the cache.

fn complete(&self, key: K, value: V, index: DepNodeIndex)

fn iter(&self, f: &mut dyn FnMut(&Self::Key, &Self::Value, DepNodeIndex))

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.
