Enum EvictionPolicy 

pub enum EvictionPolicy {
    Lru,
    Fifo,
    None,
}

Eviction strategy applied by the rotator when the cache is over budget.

Variants

Lru

Least-recently-used (based on last_accessed_ms in the index).

Fifo

First-in-first-out (based on downloaded_at_ms in the index).

None

Do not evict anything — useful for tests or when an external janitor is managing cache size.

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
