What is the best way to get the full url that Deno.serve() is running on?

If I have:

Deno.serve(
    { port: 1993, hostname: '0.0.0.0' }, 
    (_req) => new Response("Hello, world")
);

Deno.serve(
    { port: 1993, hostname: '0.0.0.0' }, 
    (_req) => new Response("Hello, world")
);

Deno.serve(
    { port: 1993, hostname: '0.0.0.0' }, 
    (_req) => new Response("Hello, world")
);

Deno.serve(
    { port: 1993, hostname: '0.0.0.0' }, 
    (_req) => new Response("Hello, world")
);

I know the url will be:

http://0.0.0.0:1993

http://0.0.0.0:1993

http://0.0.0.0:1993

http://0.0.0.0:1993 . Is there something in the

Deno.*

Deno.*

Deno.*

Deno.* API that I can reference to get it though?
