Struct EdgeCache 

pub struct EdgeCache { /* private fields */ }

LRU + version + TTL cache. Cheap to clone via Arc.

Implementations

impl EdgeCache

pub fn new(max_entries: usize) -> Self

pub fn next_version(&self) -> u64

Mint a fresh logical version. Used by the home when assigning version stamps to writes; also used by the cache itself when inserting locally-cached entries.

pub fn get(&self, key: &CacheKey) -> Option<CacheEntry>

Look up a cache entry. Returns None on miss or expired TTL. Bumps the LRU on hit; increments hit/miss counters either way.

pub fn insert(&self, key: CacheKey, entry: CacheEntry)

Insert / overwrite an entry. Triggers LRU eviction if over capacity.

pub fn invalidate(&self, up_to_version: u64, tables: &[String]) -> u64

Drop every entry whose version <= up_to_version AND whose tables overlaps with tables (empty tables invalidates every entry meeting the version bound). Returns the count dropped.

pub fn stats(&self) -> EdgeCacheStats

pub fn insert_with(&self, key: CacheKey, entry: CacheEntry)

Test-only: deterministic insert with explicit version + TTL.

Trait Implementations

impl Clone for EdgeCache

fn clone(&self) -> EdgeCache

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
