        key: K,
        replaced: Option<V>,
        evicted: Option<CacheEntry<K, V>>,

}

Factual result of one Cache command.

replaced: Option<V>

Previous value replaced at the same key, if any.

evicted: Option<CacheEntry<K, V>>

Least-recently-used entry evicted for capacity, if any.

Hit

Lookup found and refreshed one value.

Fields

key: K

value: V

Miss

Lookup found no value.

Fields

key: K

Trait Implementations

impl<K: Clone, V: Clone> Clone for CacheResult<K, V>

fn clone(&self) -> CacheResult<K, V>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<K: Debug, V: Debug> Debug for CacheResult<K, V>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<K: PartialEq, V: PartialEq> PartialEq for CacheResult<K, V>

fn eq(&self, other: &CacheResult<K, V>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
