Thoughts on moving duration to ExpiringMap::new?

What are your thoughts on moving Duration to ExpiringMap::new such that each item has a consistent expiration window.

Something akin to this:

let mut x = ExpiringMap::new(Duration::from_secs(60));
x.insert("v", "b");

If you are ok with this idea, I'll happily submit a PR for it.

I think this is reasonable. Just an Option on the struct.

I'm not sure what you're looking for in an Option on the struct. I submitted a PR (see link) that uses a duration during construction.

I wouldn’t want to preclude setting a different TTL for each key.
