Struct shared_lru::LruCache

pub struct LruCache<K, V> { /* fields omitted */ }

Implementations

impl<K, V> LruCache<K, V> where
    K: MemorySize + Eq + Hash + Simple,
    V: MemorySize + Simple, 

pub fn insert(&self, key: K, value: V) where
    K: Clone, 

pub fn get(&self, k: &K) -> Option<ValueRef<'_, K, V>>

pub fn get_or_insert(
    &self,
    k: K,
    insert_with: impl FnOnce() -> V
) -> Option<ValueRef<'_, K, V>> where
    K: Clone, 

Returns an Option because the resulting value may be too large to fit inside the allowed space. If the value is small enough, this will always return Some.
