Struct IntoIter

pub struct IntoIter<K, A: Allocator = Global> { pub(in ::collections::hash::set) base: IntoIter<K, A> }

An owning iterator over the items of a HashSet.

This struct is created by the into_iter method on HashSet (provided by the IntoIterator trait). See its documentation for more.

Examples

use std::collections::HashSet;

let a = HashSet::from([1, 2, 3]);

let mut iter = a.into_iter();
