Trait Middleware

pub trait Middleware<I, O>:
    Send
    + Sync
    + 'static {
    // Required method
    fn call<'life0, 'async_trait>(
        &'life0 self,
        input: I,
    ) -> Pin<Box<dyn Future<Output = O> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

Middleware that performs an operation.
