Enum generational_cache::cache::Eviction

pub enum Eviction<K, V> {
    Block {
        key: K,
        value: V,
    },
    Value(V),
    None,
}

The outcome of an eviction from a cache.

Evictions occur in cache implementations on insert operations in a maxed out cache. This happens to make space for the just inserted key/value pair.

Variants

Block

Fields

key: K

value: V

Block eviction with evicted key/value pair on a key/value insertion with an unique key.

Value(V)

Value eviction on insertion with a key already existing in the cache.

None

No eviction when the cache is not maxed out.

Trait Implementations

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

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

Formats the value using the given formatter.

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

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

This method tests for self and other values to be equal, and is used by ==.

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

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