the two epiphanies i had along the way were: (1) to get something out of an

Arc

, you have to call a method on it, for some reason (2) to get something into a future, you have to do a

.clone()

then a

move |...| { ... }

and it's easy! (shudders thinking of java)

What do you mean by get something out of?

let (a, b) = x.clone()

causes a type error if

x

is an

Arc<(A, B)>

let (a, b) = *x.clone() This is not an Arc thing, it's a Deref thing: https://doc.rust-lang.org/book/ch15-02-deref.html

I was looking for that page!!!! I'd read it once and had kept searching for Arc and not finding it. this is a lesson in itself
