-# Chunked transfer encoding
-
-Chunked encoding on a response can be enabled with `HttpResponseBuilder::chunked()`.
-This takes effect only for `Body::Streaming(BodyStream)` or `Body::StreamingContext` bodies.
-If the response payload compression is enabled and a streaming body is used, chunked encoding
-is enabled automatically.
