Are Windows and MacOS out of scope? I ask because the CI is failing for those platforms.

It is a problem of one of the rust libraries. I assume it will be fixed over time. If it doesn't we have to figure out what to do.

I'm not sure how polished this program is supposed to be, but for this review I'm going to assume it's supposed to be "releaseable" and consumable (for trying it out) by a user.

Calling the program with --help prints this line as the help output:

Arguments parser

Usage: domain-simple-proxy <CONFIG>

Arguments:
  <CONFIG>  Configuration

Options:
  -h, --help     Print help
  -V, --version  Print version

When publishing this, there should probably also be a config documentation. But the examples might be enough for now.

The code does what is should 👍
The examples have a few mistakes, and the configuration lacks documentation.
I have a few notes on code "quality" (but those won't be merge blocking).

Otherwise, great work.
