Source: https://github.com/zaczero/lrucache-rs/blob/main/README.md

Demonstrates the basic usage of the LRUCache class from the lrucache_rs library. It shows how to initialize a cache with a maximum size, add key-value pairs, and retrieve values, including checking for expired items.

```python
from lrucache_rs import LRUCache

cache: LRUCache[str, int] = LRUCache(maxsize=2)
cache['1'] = 1
cache['2'] = 2
cache['3'] = 3
assert cache.get('1') is None
assert cache.get('2') == 2
assert cache.get('3') == 3
```
