DNS lookup

[SixoneKui]

Hi, I am moving from js to rust.
With the JS HTTPs module, there is a way to set up a lookup function in http connection and thereby, with any domain, I can specify the IP ( the usecase is cloudflare , which matches multiple IPs to a domain but I want only connect one ).

Can I do this with hyper?

In addition, how do I enable "keepalive"? Just add the header?
Thank you very much.

You probably want to use reqwest, which does have a resolve options. It will use keep-alive automatically.
