Module head 

Available on crate features http and std only.

Standalone HTTP/1 message-head parsing and encoding.

This module handles only a request or response line plus header fields. It deliberately does not infer or encode an HTTP body framing mode, which makes it suitable for protocols such as ICAP that carry HTTP heads while framing the associated entity body themselves.
