Trait FutureFn 

pub trait FutureFn<T>:
    Fn() -> FutureBox<T>
    + Send
    + Sync { }

A trait for thread-safe, reference-counted closures that produce a boxed future.

This trait is used for storing and executing asynchronous operations that need to be sendable across threads, such as in the server’s request processing pipeline.
