Struct borsh::maybestd::collections::hash_map::Drain1.6.0[][src]

pub struct Drain<'a, K, V> where
    K: 'a,
    V: 'a, 
{ /* fields omitted */ }

A draining iterator over the entries of a HashMap.

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

Example

use std::collections::HashMap;

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