Implementations

impl NodeCache

pub fn new(max_memory: usize, policy: EvictionPolicy) -> Self

Create a new node cache with a given memory budget and eviction policy.

pub fn lru(max_memory: usize) -> Self

May evict existing entries if the memory budget is exceeded.

pub fn get(&mut self, key: &CacheKey) -> Option<&[u8]>

Get a reference to cached data.

pub fn contains(&self, key: &CacheKey) -> bool

Check if a key is present without updating access stats.

pub fn invalidate(&mut self, key: &CacheKey) -> bool

Remove a specific key from the cache.

pub fn invalidate_node(&mut self, node_id: u64)

Invalidate all entries for a given node.

pub fn clear(&mut self)

Clear all entries.

pub fn len(&self) -> usize

Current number of entries.

pub fn is_empty(&self) -> bool

Whether the cache is empty.

pub fn memory_usage(&self) -> usize
