Enum EvictionPolicy 

pub enum EvictionPolicy {
    LRU,
    FIFO,
    LFU,
    None,
}

Strategy for evicting cache entries when limits are reached

Variants

LRU

Least Recently Used - evict entries that haven’t been accessed recently

FIFO

First In First Out - evict oldest entries first

LFU

Least Frequently Used - evict entries with lowest access count

None

No automatic eviction - only manual invalidation

Implementations

impl EvictionPolicy

pub fn description(&self) -> &str

Get a description of the policy

Trait Implementations

impl Clone for EvictionPolicy

fn clone(&self) -> EvictionPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EvictionPolicy

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

Formats the value using the given formatter.

impl Default for EvictionPolicy

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for EvictionPolicy

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for EvictionPolicy

fn eq(&self, other: &EvictionPolicy) -> 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.

impl Serialize for EvictionPolicy

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
