Struct StorageCache 

pub struct StorageCache { /* private fields */ }

Multi-level cache for nodes and edges

Provides LRU-based caching with automatic eviction and TTL support. All operations are async and thread-safe.

Implementations

impl StorageCache

pub fn new() -> Self

Create a new storage cache with default settings

Default configuration:

• Node cache: 10,000 entries
• Edge cache: 50,000 entries
• TTL: 5 minutes

pub fn with_capacity(node_capacity: u64, edge_capacity: u64) -> Self

Create a cache with custom capacities

pub fn with_ttl(ttl_secs: u64) -> Self

Create a cache with custom TTL

pub async fn get_node(&self, id: &NodeId) -> Option<Node>

Get a node from cache

pub async fn insert_node(&self, id: NodeId, node: Node)

Insert a node into cache

pub async fn invalidate_node(&self, id: &NodeId)

Remove a node from cache

pub async fn get_edge(&self, id: &EdgeId) -> Option<Edge>

Get an edge from cache

pub async fn insert_edge(&self, id: EdgeId, edge: Edge)

Insert an edge into cache

pub async fn invalidate_edge(&self, id: &EdgeId)

Remove an edge from cache

pub async fn stats(&self) -> CacheStats

Get cache statistics

Returns current cache sizes. Note that hit/miss rates are not tracked by default in moka cache to minimize performance overhead.

pub fn clear(&self)

Clear all caches

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for StorageCache

fn default() -> Self
