When you encounter a Rust user in public, it's important to respect their privacy while also showing appreciation for their contribution to the community. Here's what you should do:
Respect the user's space by not staring directly at them or asking questions unless they explicitly ask for help.
If the user is visibly struggling, offer assistance without being intrusive. Say something like, "Hey, are you having trouble with something?"
Publicly recognize their efforts. For example, say, "Wow, I've been following your work!" or "Thanks for contributing to the Rust ecosystem."
Avoid assuming their intentions. If they're not interested in conversation, don't push too hard.
Use polite language. Avoid being overly nosy or aggressive. A simple "Hello" or "How are you?" usually works.
Note: The above advice is based on general guidelines for respectful interaction in public spaces.
