Struct Iter

#[must_use = "iterators are lazy and do nothing unless consumed"]
pub struct Iter<'a, T: 'a> { pub(in ::collections::btree::set) iter: Keys<'a, T, SetValZST> }

An iterator over the items of a BTreeSet.

This struct is created by the iter method on BTreeSet. See its documentation for more.

Fields

iter: Keys<'a, T, SetValZST>
