Implementations

impl LayerCache

pub fn new(max_entries: usize) -> Self

pub fn get(&self, digest_hex: &str) -> Option<&CachedLayer>

Get a cached layer by digest hex.

pub fn insert(&mut self, layer: CachedLayer) -> bool

Insert a layer into the cache. Returns false if cache is full.

pub fn add_ref(&mut self, digest_hex: &str) -> bool

Increment reference count for a layer.

pub fn release(&mut self, digest_hex: &str) -> bool

Decrement reference count. Removes the entry if it reaches zero.

pub fn entry_count(&self) -> usize

pub fn is_full(&self) -> bool
