VirtualBox Host-Only Static IP

My typical setup for a development box in VirtualBox uses two NICs. The first uses NAT to allow the box to communicate with the outside world through my host computer’s network connection. (NAT is the default, so shouldn't require any setup.) The second is a "host-only" connection that allows my host and guest to interact.

To create a host-only connection in VirtualBox, start by opening the preferences in VirtualBox. Go to the "Network" tab, and addd a Host-only Network. Modify the host-only network, and disable DHCP. Make a note of the IP address. (Feel free to set the IP address as well, if you like.)

Next, assign this host-only adapter to the virtual machine. Select the VM and press "Settings". Go to the "Network" tab, and select "Adpater 2". Enable the adapter, set it to a "Host-only Adapter", and select the adpater you created above.

No Box<T>

tl;dr: Avoid Box<T> in general.

Actually, this rule is so important that the Rust Pointer Guide explicitly says the same. Therefore without a further ado, you should avoid Box<T> except for these three cases:

1. When you absolutely need a trait object (Box<Trait>). But review carefully to see if it is indeed absolutely needed; you may try to generalize things too far, for example.

2. When you have a recursive data structure. This may be mandatory when you have an inherently recursive data (e.g. scene graph), but it may also be a sign of the premature optimization. Again, review carefully to see if you need to write a separate data structure yourself, and use the collection crate if possible.
