#2I think Steve Klabnik could clarify this, but the book at that link is in the process of being rewritten. I think it might be good to wait until it is. I personally found it slightly difficult to follow compared to other options like the soon to be published Programming Rust.

A quick search turned up this: https://doc.rust-lang.org/book/closures.html#move-closures.

#6Does Rust have a way to work with SIMD concurrency as opposed to just fork/join concurrency? Something along the lines of how openmp or cilk let you do a parallel for all?

A simple google search would have told you that there is work being done the introduce simd in Rust. There appear to be some basics there right now but not much if i understood my quick search.
