## Usage
```
use thread_safe_cache::*;
use std::thread;
use std::thread::sleep;
use std::time::Duration;
fn main() {
let mut builder: BuilderEmbedded<String, i32> = BuilderEmbedded::init();
builder.max_size(1000);
let mut cache_init = builder.build();
let mut cache1 = cache_init.clone();
thread::spawn(move || {
cache1.put("key1".to_string(), 1);
cache1.put_exp("key2".to_string(), 2, 3000);
});
let mut cache2 = cache_init.clone();
let t = thread::spawn(move || {
sleep(Duration::from_millis(2000));
cache2.rm("key1".to_string());
cache2.get("key2".to_string())
});
assert_eq!(t.join().unwrap(),Some(2));
let mut cache3 = cache_init.clone();
assert_eq!(cache3.get("key2".to_string()), Some(2));
sleep(Duration::from_millis(2000));
assert_eq!(cache3.get("key2".to_string()), None);
}
```
