Module cache 

Available on crate feature cache only.

In-memory cache with per-source TTL, metrics, and invalidation.

Wraps moka to provide a concurrent, async-friendly cache with TinyLFU eviction. Matches hyperi-pylib’s cache module API: per-source TTL configuration, get/set/invalidate_source.

Config Cascade

cache:
  max_capacity: 10000
  default_ttl_secs: 3600
  source_ttls:
    http: 86400
    db: 1800
    search: 3600

Usage

use hyperi_rustlib::cache::{Cache, CacheConfig};

#[tokio::main]
async fn main() {
    let cache = Cache::new(CacheConfig::default());

    // Set with source-specific TTL
    cache.set("http", "https://api.example.com", "response_data").await.expect("cache set");

    // Get
    if let Some(value) = cache.get::<String>("http", "https://api.example.com").await {
        println!("cached: {value}");
    }

    // Invalidate all entries for a source
    cache.invalidate_source("http").await;
}
