[][src]Struct scale_info::prelude::collections::hash_map::IntoKeys

pub struct IntoKeys<K, V> { /* fields omitted */ }
🔬 This is a nightly-only experimental API. (map_into_keys_values)

An owning iterator over the keys of a HashMap.

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

Example

#![feature(map_into_keys_values)]

use std::collections::HashMap;

let mut map = HashMap::new();
map.insert("a", 1);
let iter_keys = map.into_keys();
