///
/// ```ignore
/// pub fn middleware(
///     req: HttpRequest,
///     params: &RouteParams,
///     next: &dyn Fn(HttpRequest, &RouteParams) -> HttpResponse<'static>,

///     // Pre-processing: inspect or modify request
///     let mut response = next(req, params);
///     // Post-processing: inspect or modify response
///     response
/// }
/// ```
