4//! Definition and implementation of [`ListViewVector`] and [`ListViewVectorMut`].
5//!
6//! A [`ListViewVector`] represents a collection of variable-width lists, where each list can
7//! contain a different number of elements.
8//!
9//! The structure uses separate offset and size vectors to track the boundaries of each list
10//! within the flat elements array. This allows for efficient access to individual lists without
11//! copying data.  This is similar to Apache Arrow's `ListView` type.
