`Cache`



```python theme={null}
Cache(config: dict[str, Any])
```

A wrapper class for managing cache configuration and instances.
This class provides a unified interface for creating and interacting with
different types of cache (e.g., Redis, Disk). It abstracts the underlying
cache implementation details, providing methods for cache operations.
Attributes: 
    config (Dict\[str, Any]): A dictionary containing cache configuration.
    cache: The cache instance created based on the provided configuration.
Initialize the Cache with the given configuration.
Validates the configuration keys and creates the cache instance.


Parameters:

| Name     | Description               |
| -------- | ------------------------- |
| `config` | **Type:** dict\[str, Any] |
