Ipv6

[hellow554]

You are currently only allow Ipv4 access to the host, but no IPv6.
I would like to see either a command line argument to enable one/both or make dual stack the default :)

Good idea. Will do. Of course, you can also go ahead and make a PR if you would like to take a stab at this yourself.

I just discovered, that it is already capable of running Ipv6, just pass e.g. :: as interface and it will serve it just fine.

cargo run --release -- -i '::' .
    Finished release [optimized] target(s) in 1.25s
    Running `target/release/miniserve -i '::' .`
miniserve is serving your files at http://:::8080
Currently serving path /tmp/tmp.Mkfpy6fbam/miniserve

(please note the "wrong" format:

http://:::8080
       ^-- here

it should be http://[::]:8080)

There is a problem though.
On linux, it will bind on both, IPv4 and IPv6. On windows on the otherhand, it will only bind on either (source).
So I have a few ideas in mind.

1. Check if it is an IPv6 addr and try to bind on both. This will mean we get an error on Linux, but not on windows. Shall be check the OS (on compile- or runtime?) and do different things?
2. Check explicitly in is_valid_interface for Ipv4 addr (which is trivial :) ) and only accept IPv4 addr on --if and add another option (maybe --if6)?
3. When default is given (no --if parameter at all) do a double bind, and only if either option is given (--if or --if6) bind to that protocol but not on the other (unless both options are given)
4. ??? -> Profit?

One more note: If it is an IPv6, the URL should be displayed like this: `http://[::]:8080'.

@hellow554 Thanks for considering this so thoroughly!

About your 1.: I don't quite understand. How would you even go about binding on both interfaces if you provide an IPv6? It could just be that an interface does not even have an IPv4 even if it has an IPv6. Basically, I think that if an explicit IPv4 or IPv6 is given, we should not try to bind on anything except those provided.

I think --if should accept both IPv6 and IPv4. There doesn't really seem to be an issue with that. Also, we should allow for --if to be called multiple times.

3. I agree with this. It should try to bind on all interfaces on both protocols in the correct way on all OS.

Fixed in v0.2.0.
