@wizzwizz4 It's an sqlite dependency that apparently wants to work even when sqlite is compiled as single thread only, so it doesn't implement `Send`.

I could have switched to another dependencies, but now I'm trying to rewrite my struct as an actor that lives in its own thread and just sends messages to other threads. In my case this also simplifies other things.

But it's a pain to wrap everything in messages, so I'm letting Claude (the LLM) do the work...
