Struct Drain
pub struct Drain<'a, T> { /* private fields */ }A draining iterator over the items of an IndexSet.
This struct is created by the IndexSet::drain method.
See its documentation for more.
Implementations
impl<'a, T> Drain<'a, T>
fn as_slice(&self) -> &Slice<T>Returns a slice of the remaining entries in the iterator.
