Trait ListLikeArray 

pub trait ListLikeArray: Array {
    // Required methods
    fn values(&self) -> &Arc<dyn Array> ;
    fn element_range(&self, index: usize) -> Range<usize>;
}

A trait for Arrow list-like arrays, abstracting over GenericListArray, GenericListViewArray, and FixedSizeListArray.

This trait provides a uniform interface for accessing the child values and computing the element range for a given index, regardless of the underlying list layout (offsets, offsets+sizes, or fixed-size).

Required Methods

fn values(&self) -> &Arc<dyn Array>

Returns the child values array.

fn element_range(&self, index: usize) -> Range<usize>

Returns the start and end indices into the values array for the list element at index.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
