Struct Drain

pub struct Drain<'a, K, V> { /* private fields */ }

A draining iterator over the entries of an IndexMap.

This struct is created by the IndexMap::drain method. See its documentation for more.

Implementations

impl<'a, K, V> Drain<'a, K, V>

fn as_slice(&self) -> &Slice<K, V>

Returns a slice of the remaining entries in the iterator.
