Struct RequestIdLayer 

pub struct RequestIdLayer;

Legacy Tower layer that adds an x-request-id response header when absent.

Incoming request IDs are propagated to the response unless the inner service already set a response ID. Requests without an ID receive a generated UUID v4 value.

This layer does not validate inbound IDs and does not populate RequestContext. Prefer validated_request_id_layer for production API defaults, UUID v4 generation, strict/permissive validation, request extension insertion, and consistent error responses.
