Cache

Struct Cache 

Source
pub struct Cache<B, CM = NoopConcurrencyManager, O = DisabledOffload> { /* private fields */ }
Expand description

Pre-configured cache with backend, policy, concurrency manager, and offload manager.

Use Cache::builder() to create a new cache configuration.

§Example

use hitbox_fn::Cache;
use hitbox::policy::PolicyConfig;
use hitbox_moka::MokaBackend;
use std::time::Duration;

let backend = MokaBackend::builder().max_entries(1000).build();
let policy = PolicyConfig::builder().ttl(Duration::from_secs(60)).build();

let cache = Cache::builder()
    .backend(backend)
    .policy(policy)
    .build();

// Use with cached functions
let result = my_cached_function(arg1, arg2)
    .cache(&cache)
    .await;

// With offload manager for Stale-While-Revalidate
use hitbox::offload::OffloadManager;

let cache = Cache::builder()
    .backend(backend)
    .policy(policy)
    .offload(OffloadManager::with_defaults())
    .build();
