Does the client written with Hyper FFI support chunked sending and receiving?

[spongehah]

I have a question: Does the client written with Hyper FFI support chunked sending and receiving? I noticed there's a function named print_each_chunk in capi/examples/client.c, but when I make a request to httpbin.org/post, the response body's request headers don't include 'Transfer-Encoding: chunked'.
