Struct SetForwardedHeadersLayer

pub struct SetForwardedHeadersLayer<T = Forwarded> { /* private fields */ }
Expand description

Layer to write Forwarded information for this proxy, added to the end of the chain of forwarded information already known.

This layer can set any header as long as you have a ForwardHeader implementation for the header you want to set. You can pass it as the type to the layer when creating the layer using SetForwardedHeadersLayer::new. Multiple headers (in order) can also be set by specifying multiple types as a tuple.

The following headers are supported out of the box with each their own constructor:

The “by” property is set to rama by default. Use SetForwardedHeadersLayer::forward_by to overwrite this, typically with the actual IPv4/IPv6 address of your proxy.

Rama also has the following headers already implemented for you to use:

X-Real-Ip, X-Client-Ip, Client-Ip, CF-Connecting-Ip and True-Client-Ip.

There are no SetForwardedHeadersLayer constructors for these headers, but you can use the SetForwardedHeadersLayer::new constructor and pass the header type as a type parameter, alone or in a tuple with other headers.

§Example

This example shows how you could expose the real Client IP using the X-Real-IP header.

use rama_net::stream::SocketInfo;
use rama_http::Request;
use rama_core::service::service_fn;
use rama_http::{headers::XRealIp, layer::forwarded::SetForwardedHeadersLayer};
use rama_core::{Context, Service, Layer};
use std::convert::Infallible;


async fn svc(_ctx: Context<State>, request: Request<Body>) -> Result<(), Infallible> {
    // ...
}

let service = SetForwardedHeadersLayer::<XRealIp>::new()
    .layer(service_fn(svc));

service.serve(ctx, req).await.unwrap();
