Implementations

impl Router

pub fn new( configured_backend_timeout: Duration, configured_connect_timeout: Duration, ) -> Self

pub fn backend_from_request( &mut self, cluster_id: &str, frontend_should_stick: bool, context: &mut HttpContext, selector: &mut dyn BackendSelector, ) -> Result<BackendId, BackendConnectionError>

Pick the backend for an already-routed request and stamp its identity onto the request’s HttpContext.

Takes no listener handle: every listener-derived value this needs — sticky_name above all — is already on the HttpContext that Context::create_stream filled when the request arrived, and reading the listener again here would be exactly the mid-request reload leak LIFECYCLE.md §2.5 rules out.

Takes no proxy handle either: the backend set arrives as selector, a capability borrowed for this one call (see BackendSelector).

Returns the chosen backend, reserved but not dialled: the caller connects to BackendId::address (#1684).
