Enum Priority 

pub enum Priority {
    Low,
    Normal,
    High,
    NeverRemove,
}

Memory-eviction priority hint, mirroring CacheItemPriority.

The in-memory backend (moka) uses a TinyLFU policy and does not honour an explicit priority; this is retained for API parity and forwarded where a backend can use it. NeverRemove entries (e.g. internal tag markers) are kept in a dedicated never-evicting structure instead.

Variants

Low

Evicted first under memory pressure.

Normal

The default priority.

High

Evicted last under memory pressure.

NeverRemove

Never evicted by the size policy.
