A trait for referencable linear array types

Required Methods

fn as_slice(&self) -> &[T]

The underlying elements as slice

fn len(&self) -> usize

The length of the wrapped elements

fn is_empty(&self) -> bool

Whether self is empty or not

fn get(&self, index: usize) -> Option<&T>

Gets an element

fn get_n<Range>(&self, range: Range) -> Option<Array<&[T]>>

where Range: RangeBounds<usize>,

Gets a subrange

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

Returns a reference to the first element

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

Returns a reference to the last element

fn iter(&self) -> SliceIter<'_, T>

Returns an iterator that references the elements

fn clone_to<Target>(&self, target: &mut Target) -> Result<(), BufferTooSmall>

where Target: ArrayMut<T>, T: Clone,

Clones self to target

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.
