fs::exists() was a nice little improvement that I didn't know about until I read this announcement.
It's a subtle difference between that and
path::exists().path::exists()==falsemight just mean you can't use it (if path::exists() cannot access a file due to e.g. permissions, it'll return false)fs::exists()==Ok(false)means it's definitely not there (permissions error will cause an Err to be returned)
