Usage
场景 1:定义缓存及清理时间
use safe_cache::{Cache, async_cleanup_task}; use std::sync::Arc;
async fn main() {
let cache = Arc::new(Cache::new());
let cache_clone = Arc::clone(&cache);
async_cleanup_task(cache_clone, 10).await;
cache.set("number".to_string(), 42, 20);
cache.set("list".to_string(), vec![1, 2, 3], 60);
cache.set("text".to_string(), "Hello, Rust!".to_string(), 0);
println!("Value for number: {:?}", cache.get::<u16>("number"));
println!("Value for list: {:?}", cache.get::<Vec<i32>>("list"));
println!("Value for text: {:?}", cache.get::<Vec<i32>>("text"));
thread::sleep(Duration::from_secs(30));
println!("After clearing expired entries:");
println!("Value for number: {:?}", cache.get::<i32>("number"));
println!("Value for text: {:?}", cache.get::<String>("text"));
cache.remove("text");
println!("Value for text: {:?}", cache.get::<String>("text"));
}
场景 2:当做全局 config 来使用,不启用清理任务
use safe_cache::Cache;
use std::sync::Arc;
fn main() {
let cache = Arc::new(Cache::new());
cache.set("number".to_string(), 42, 0);
cache.set("list".to_string(), vec![1, 2, 3], 0);
cache.set("text".to_string(), "Hello, Rust!".to_string(), 0);
println!("Value for number: {:?}", cache.get::<i32>("number"));
println!("Value for list: {:?}", cache.get::<Vec<i32>>("list"));
println!("Value for text: {:?}", cache.get::<Vec<String>>("text"));
}
