I think you could even get rid of the iter() and the collect() since it's a small fixed size array.

Yep [T;N] has a direct implementation of map. "{:?}" is necessary because arrays aren't Display but you could get around that by saying

["1", "not a number", "3"].map(|n| println!("{}", n.parse().unwrap_or(0)));

but now I'm golfing. Also

for n in ["1", "not a number", "3"] {
   println!("{}", n.parse().unwrap_or(0))
}

is more idiomatic I shouldn't let my Haskell get the better of me. That does use Iterator, not that it makes a difference here.
