Function remove_hop_by_hop_headers 

pub fn remove_hop_by_hop_headers(headers: &mut HeaderMap)

Available on crate features http and std only.

Remove all hop-by-hop headers from an HTTP message.

In addition to the known connection-specific fields, this removes every field nominated by Connection except Early-Data. Use HopByHopHeaderContext::take when upgrade, trailer, or TE: trailers metadata has to be restored for a newly originated hop. This direction-free helper preserves request-field exceptions; use remove_hop_by_hop_response_headers for responses.
