early version of rust code-of-conduct

gistfile1.txt

h2. Conduct

* Please be kind and courteous. There's no need to be mean or rude.
* Respect that people have differences of opinion and that every design or implementation choice carries a trade-off and numerous costs. There is seldom a right answer.
* Please keep unstructured critique to a minimum. If you have solid ideas you want to experiment with, follow the language-change process (see below). Noisy debate just impedes progress.
* We will exclude you from interaction if you insult, demean or harass anyone. That is not welcome behaviour.
* Likewise any spamming, trolling, flaming, baiting or other attention-stealing behaviour.
