//! Basic usage example for threatflux-cache

use serde::{Deserialize, Serialize};
use threatflux_cache::prelude::*;

#[derive(Debug, Clone, Serialize, Deserialize)]
struct User {
    id: u64,
    name: String,
    email: String,
}

#[tokio::main]
#[allow(clippy::type_complexity)]
async fn main() -> std::result::Result<(), Box<dyn std::error::Error>> {
    // Create a cache with default configuration
    let config = CacheConfig::default()
        .with_max_entries_per_key(10)

    let cache: Cache<String, User> = Cache::with_config(config).await?;

    // Store some users
    let user1 = User {
        id: 1,
        name: "Alice".to_string(),
        email: "alice@example.com".to_string(),

    cache.put("user:1".to_string(), user1.clone()).await?;
