fakecloud_cloudfront::dataplane

Struct CloudFrontDataPlane 

Source 
pub struct CloudFrontDataPlane { /* private fields */ }
Expand description

The CloudFront data plane: serves enabled distributions on the main listener, routed by Host. Constructed once at server startup and installed as an outer middleware; see CloudFrontDataPlane::serve.

Implementations§

Source§

impl CloudFrontDataPlane

Source

pub fn new(state: SharedCloudFrontState, server_port: u16) -> Arc<Self> ⓘ

Build the data plane. server_port is fakecloud’s own listen port, used to reach S3-website origins served by this same process. Returns an Arc for sharing into the axum middleware layer. Cheap and infallible; if the tuned reqwest client fails to build (should not happen), the plane declines to serve (enabled = false) so requests still dispatch normally rather than being proxied through a degraded client.

Source

pub async fn serve(&self, req: Request<Body>) -> Result<Response, Request<Body>>

Serve a request iff its Host matches an enabled distribution.

  • Ok(resp) – the request was viewer traffic for a distribution and was proxied to the resolved origin (the body has been consumed).
  • Err(req) – the Host matches no distribution (or the plane is disabled); the request is returned untouched for normal AWS dispatch.

The Host check happens on the request headers before the body is touched, so pass-through traffic (all AWS API calls, /_fakecloud/*) is never buffered.
