Required Associated Types

type Iter<'a>: Iterator<Item = &'a T> + DoubleEndedIterator + ExactSizeIterator where Self: 'a, T: 'a

type IterMut<'a>: Iterator<Item = &'a mut T> + DoubleEndedIterator + ExactSizeIterator where Self: 'a, T: 'a

type IntoIter: Iterator<Item = T> + DoubleEndedIterator + ExactSizeIterator

Required Methods

fn into_iter_elements(self) -> Self::IntoIter

fn iter_elements(&self) -> Self::Iter<'_>

fn iter_elements_mut(&mut self) -> Self::IterMut<'_>

fn len(&self) -> usize

fn last(&self) -> Option<&T>

Provided Methods

fn reset(&mut self)

fn is_empty(&self) -> bool

fn first_non_zero_index(&self) -> Option<usize>

Returns the first element that is not equal to the default value.

fn last_non_zero_index(&self) -> Option<usize>

Returns the last element that is not equal to the default value.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
