Hello,
Is it me or there is no interface provided for a HTTP Client to stream, via a callback, the body of the Request ?

In the http::client API, you have
response_ = client_.get(request_, _body_handler=callback), which is used to process the body of the response.

But there is no function in the http::request API to provide a callback to be called when it needs body chunks for the request ?

Thank you.
