    What a non-story.

    Lemmy project set wild unrealistic expectations on GItHub project: 1) "high performance’, maybe the Rust code but PostgreSQL logic is the ORM madness. 2) “full erase” while sending all your public comments and posts to ActivePub without agreement on concept of delete.

      unrealistic expectations on GItHub project: 1) "high performance

      For sure. That seems to be the go to phrase for anything developed in Rust. By itself, Rust isn’t any safer or faster than another similar language; it takes a good developer to make it work well.

      Just because it’s written in Rust doesn’t make your app safe, or performant. Just like because your app is written in C, doesn’t mean it’s buggy and insecure.

        That is with hand-optimized person_id = $1, which the Rust code does not do.
