Struct CacheInvalidator 

pub struct CacheInvalidator<K> { /* private fields */ }

Tracks dependencies between cache keys and supports cascade invalidation.

When key A depends on key B, invalidating B also invalidates A.

Implementations

impl<K> CacheInvalidator<K>

where K: Eq + Hash + Clone,

pub fn new() -> Self

Create a new invalidator with no dependencies.

pub fn add_dependency(&self, dependency: K, dependent: K)

Register that dependent depends on dependency.

When dependency is invalidated, dependent will also be invalidated.

pub fn remove_dependency(&self, dependency: &K, dependent: &K)

Remove a specific dependency relationship.

pub fn cascade(&self, root: &K) -> InvalidationResult<K>

Compute the full set of keys that should be invalidated when root is invalidated, following the dependency graph transitively.

pub fn clear(&self)

Clear all dependency tracking.

pub fn dependency_count(&self) -> usize

Number of keys that have dependents registered.

pub fn has_dependents(&self, key: &K) -> bool

Check if a key has any dependents.

Trait Implementations

impl<K: Eq + Hash + Clone> Default for CacheInvalidator<K>

fn default() -> Self

Returns the “default value” for a type.
