Struct Union
#[must_use = "this returns the union as an iterator, without modifying either input set"]
pub struct Union<'a, T: 'a>(pub(in ::collections::btree::set) MergeIterInner<Iter<'a, T>>);A lazy iterator producing elements in the union of BTreeSets.
This struct is created by the union method on BTreeSet.
See its documentation for more.
