Struct Manager

pub struct Manager { /* private fields */ }

A simple LRU eviction manager

The implementation is not optimized. All operations require global locks.

Implementations

impl Manager

pub fn new(limit: usize) -> Self

Create a new Manager with the given total size limit limit.

Trait Implementations

impl EvictionManager for Manager

fn total_size(&self) -> usize

Total size of the cache in bytes tracked by this eviction manager

fn total_items(&self) -> usize

Number of assets tracked by this eviction manager

fn evicted_size(&self) -> usize

Number of bytes that are already evicted

fn evicted_items(&self) -> usize

Number of assets that are already evicted

fn admit( &self, item: CompactCacheKey, size: usize, _fresh_until: SystemTime, ) -> Vec<CompactCacheKey>

Admit an item

fn remove(&self, item: &CompactCacheKey)

Remove an item from the eviction manager.

fn access( &self, item: &CompactCacheKey, size: usize, _fresh_until: SystemTime, ) -> bool

Access an item that should already be in cache.

fn peek(&self, item: &CompactCacheKey) -> bool

Peek into the manager to see if the item is already tracked by the system

fn save<'life0, 'life1, 'async_trait>( &'life0 self, dir_path: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Serialize to save the state of this eviction manager to disk

fn load<'life0, 'life1, 'async_trait>( &'life0 self, dir_path: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

The counterpart of Self::save().
