pub fn dedup_values<'a, I>(items: I) -> Vec<VmValue>where
I: IntoIterator<Item = &'a VmValue>,Expand description
Structural de-duplication that honors values_equal, preserving
first-occurrence order.
Candidates are bucketed by value_structural_hash_key (so the common
case stays near-O(n)), then every hash hit is confirmed with
values_equal. Because the hash key is consistent with values_equal,
numerically-equal values that hash alike (e.g. 1 and 1.0) collapse to a
single entry, while hash collisions between unequal values (e.g. two NaNs
sharing a bit pattern) never merge — matching the == operator exactly.
