pub trait CacheValidator
where
    Self: Send,
{
    // Required methods
    fn allocate_slots(&mut self, slot_count: usize);
    fn is_slot_valid(&self, slot_id: usize) -> bool;

}

Validators are used when working with caches and determine for how long a specific cache entry stays valid.

Required Methods

fn allocate_slots(&mut self, slot_count: usize)

Allocate the required amount of slots used for validation

fn is_slot_valid(&self, slot_id: usize) -> bool

Checks wether or not the given slot is valid.

fn validate_slot(&mut self, slot_id: usize)

Callback from the cache implementation when a page is cached and the slot should become valid.

fn invalidate_slot(&mut self, slot_id: usize)

Callback from the caching implementation to mark a slot as invalid.

This can happen if two different cache entries fall into the same slot id.

Provided Methods

fn update_validity(&mut self)

Invoked once per Read/Write so internal state can be updated if necessary.

This is an optimization so things like std::time::Instant only need to be computed once.
