Utilities for Request object.
@deprecated Move to request-utils.
Check two Request fields equality.
import { equalsRequest } from "https://deno.land/x/http_utils@$VERSION/request.ts";

declare const url: URL;
assert(
equalsRequest(
new Request(url, { method: "HEAD" }),

If you also want to check the equivalence of the body, set the mode to strict.
