Module dial9 

Available on crate features dial9 and http and std only.

HTTP operation recording shared by HTTP/1, HTTP/2 and HTTP/3.

The backend client and core server adapter use this automatically with their dial9 feature. Use Dial9Layer around a logical request service to also correlate its retries, redirects, DNS and connection selection. Each attempt remains a child operation. Bodies retain the context after response headers; dropping a streaming response records cancellation, not successful completion. No URLs, headers or body contents are recorded.
