Struct EventInvalidationStrategy 

pub struct EventInvalidationStrategy {
    pub prefix: String,
    pub default_ttl: Duration,
    pub use_versioning: bool,
}

Event-based invalidation strategy

This strategy explicitly invalidates cache entries in response to specific events.

Fields

prefix: String

Key prefix to use

default_ttl: Duration

Default TTL for cache entries

use_versioning: bool

Whether to use versioned keys

Implementations

impl EventInvalidationStrategy

pub fn new(prefix: &str, default_ttl: Duration, use_versioning: bool) -> Self

Create a new event-based invalidation strategy

pub async fn versioned_key( &self, cache: &dyn CacheService, entity_type: &str, ) -> CacheResult<String>

Generate a versioned key if versioning is enabled

pub async fn generate_key_async( &self, cache: &dyn CacheService, entity_type: &str, entity_id: &str, ) -> CacheResult<String>

Generate a key with versioning support for async contexts
