+//! #     body::MessageBody,
+//! #     dev::{ServiceRequest, ServiceResponse, Service as _},

+//! In the more general ase, a middleware is a pair of types that implements the [`Service`] trait
+//! and [`Transform`] trait, respectively. The [`new_transform`] and [`call`] methods must return a
+//! [`Future`], though it can often be [an immediately-ready one](actix_utils::future::Ready).

+//! All the built-in middleware use this pattern with pairs of builder (`Transform`) +
+//! implementation (`Service`) types.
