Trait swagger::context::Push [−] [src]

pub trait Push<T> {
    type Result;
    fn push(self, _: T) -> Self::Result;
}

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::server::Service for MiddlewareService<T, C>
    where
        C: Push<MyItem1, Result=D>,
        D: Push<MyItem2, Result=E>,
        E: Push<MyItem3>,
        T: hyper::server::Service<Request = (hyper::Request, E::Result)>
{
    type Request = (hyper::Request, C);
    type Response = T::Response;
    type Error = T::Error;
    type Future = T::Future;
    fn call(&self, (req, context) : Self::Request) -> Self::Future {
        let context = context
            .push(MyItem1{})
            .push(MyItem2{})
            .push(MyItem3{});
        self.inner.call((req, context))
    }
}
