pub fn detect_service_headers_only(
headers: &HeaderMap,
query_params: &HashMap<String, String>,
) -> Option<DetectedRequest>Expand description
Header-only service detection. Skips the form-encoded body sniff so
the dispatch path can decide whether to stream or buffer the body
without first reading it. Returns None when only a body sniff
would succeed; the caller must then fall back to detect_service
after buffering. Used to opt streaming routes (S3 PutObject /
UploadPart, ECR OCI v2 blob upload) out of the global body cap.
