An extension trait for Readable<Vec> that provides some convenience methods.

Provided Methods

fn len(&self) -> usize

Returns the length of the inner vector.

fn is_empty(&self) -> bool

Returns true if the inner vector is empty.

fn first(&self) -> Option<<Self::Storage as AnyStorage>::Ref<T>>

Get the first element of the inner vector.

fn last(&self) -> Option<<Self::Storage as AnyStorage>::Ref<T>>

Get the last element of the inner vector.

fn get(&self, index: usize) -> Option<<Self::Storage as AnyStorage>::Ref<T>>

Get the element at the given index of the inner vector.

fn iter(&self) -> ReadableValueIterator<'_, Self>

where Self: Sized,

Get an iterator over the values of the inner vector.

Object Safety

This trait is not object safe.
