Thanks for the suggestions and explanations. I am not sure what to do in my case though. The situation is as follows. I have a struct that is populated via user input not necessarily at single instance (so that seems to rule out immutable). On the other hand while it is being populate it is only accessible from one thread so that makes using shared messy. After being populated it should be passed to the other thread and no references are kept.
You are allowed to cast to immutable if no other mutable references are used. I recommend using `assumeUnique`.
What I am doing currently is populating the struct and casting to shared when I push into a synchronized queue (no references to its data are kept in the first thread). Is what I am doing wrong and can it be achieved using message passing?
Yeah, build it like Ali says, and then cast in order to pass it. -Steve
