Type Alias DataFuture 

pub type DataFuture = Box<dyn Future<Output = ContainerResult> + Unpin + Send + 'static>;

Type alias for a boxed, dynamically dispatched Future that yields a ContainerResult. This allows storing and managing different asynchronous operations (load, sort, format) that all eventually produce a DataContainer or an error.

• dyn Future: Dynamic dispatch for different future types.
• Output = ContainerResult: The future resolves to our specific result type.
• + Unpin: Required for async/await usage in certain contexts.
• + Send + 'static: Necessary bounds for futures used across threads (like with tokio::spawn).

Aliased Type
