seen_set
A HashSet that doesn't store values, but instead only stores hashes.
This is useful when you only need to tell if you've seen a value before and you don't want to clone the value for performance reasons.
let mut seen = SeenSet::new();
for path in some_func_that_may_return_duplicate_paths() {
if !seen.insert(&path) {
continue;
}
// we haven't seen this path before
}
Note: This will be slower for values like numbers. Just use a regular HashSet for that.
