I'm the main author for these notmuch rust bindings: https://github.com/vhdirk/notmuch-rs
In making these bindings safe, it's very important to understand when memory is reclaimed by notmuch (and when not). And I'm having a hard time deducing that from the documentation. I've built a couple of c test routines, but I'm getting none the wiser from that.

For instance, when iterating messages from a thread: Can one still use a notmuch_message_t* when the thread is destroyed? Are the individual messages 'owned' by the thread, or only by the query? Same question for 'replies'.

Could someone please shed some light on this? I'd very much appreciate it.

Kind regards
