Struct IntoValues

pub struct IntoValues<K, V, A: Allocator = Global> { pub(in ::collections::hash::map) inner: IntoIter<K, V, A> }

An owning iterator over the values of a HashMap.

This struct is created by the into_values method on HashMap. See its documentation for more.

Example

use std::collections::HashMap;

let map = HashMap::from([
    ("a", 1),
]);
let iter_keys = map.into_values();

Fields

inner: IntoIter<K, V, A>
