Hey, thanks for the PR to add this event. For meetup groups, we have a script that pulls events from a list of known rust groups, (including this group)

this-week-in-rust/tools/events/rust-meetups.json

Line 53 in f5e255d

"https://www.meetup.com/rust-bern/events/",

Each week we'll get the new events from the groups in the list when we run our scripts, so no need to add these manually. I just ran the script for this week and the event is included there (#6329). Again thanks for the PR, if you have any other meetup groups feel free to submit a PR to add them to the list and let us know if you have any questions.
