This looks fine. Is there any reason for using .to_vec() instead of .iter().cloned() like std does?

Previously I tried this, but it didn't work (#1760 (comment)).

I think this is because ToSocketAddrs::Iter needs to have 'static lifetime.

tokio/tokio/src/net/addr.rs

Lines 224 to 225 in 0a42259

type Iter: Iterator<Item = SocketAddr> + Send + 'static;
type Future: Future<Output = io::Result<Self::Iter>> + Send + 'static;

That certainly sounds like a good reason. 👍
