Struct DependencyGraph 

pub struct DependencyGraph { /* private fields */ }

Dependency graph tracking which cache entries depend on which triple patterns

Implementations

impl DependencyGraph

pub fn new() -> Self

Create new dependency graph

pub fn register_dependencies( &self, cache_key: CacheKey, patterns: Vec<TriplePattern>, ) -> Result<()>

Register dependencies for a cache entry with optional TTL

pub fn register_dependencies_with_ttl( &self, cache_key: CacheKey, patterns: Vec<TriplePattern>, ttl: Option<Duration>, ) -> Result<()>

Register dependencies for a cache entry with TTL

pub fn remove_entry(&self, cache_key: &CacheKey) -> Result<()>

Remove a cache entry and its dependencies

pub fn find_expired_entries(&self) -> Vec<CacheKey>

Find all expired cache entries based on TTL

pub fn get_ttl_info( &self, cache_key: &CacheKey, ) -> Option<(Duration, Option<Duration>)>
