[−][src]Trait swagger::context::Push
Defines a method for inserting a value, changing the resulting type. Used to specify that a hyper service adds some data from the context, making it available to later layers, e.g.
struct MyItem1; struct MyItem2; struct MyItem3; struct MiddlewareService<T, C> { inner: T, marker: PhantomData<C>, } impl<T, C, D, E> hyper::service::Service for MiddlewareService<T, C> where C: Push<MyItem1, Result=D> + Send + 'static, D: Push<MyItem2, Result=E>, E: Push<MyItem3>, E::Result: Send + 'static, T: hyper::service::Service<ReqBody=ContextualPayload<hyper::Body, E::Result>> { type ReqBody = ContextualPayload<hyper::Body, C>; type ResBody = T::ResBody; type Error = T::Error; type Future = T::Future; fn call(&mut self, req : hyper::Request<Self::ReqBody>) -> Self::Future { let (head, body) = req.into_parts(); let context = body.context .push(MyItem1{}) .push(MyItem2{}) .push(MyItem3{}); let req = hyper::Request::from_parts(head, ContextualPayload { inner: body.inner, context }); self.inner.call(req) } }
