Accessors for a canonical sparse union array.

Provided Methods

fn variants(&self) -> &UnionVariants

The union’s variant schema.

fn type_ids(&self) -> &ArrayRef

The row-aligned u8 type IDs whose nulls represent outer union nulls.

fn iter_children(&self) -> impl ExactSizeIterator<Item = &ArrayRef> + '_

Iterate over sparse children in variant order.

fn children(&self) -> Arc<[ArrayRef]>

Return the sparse children in variant order.

fn child(&self, index: usize) -> Option<&ArrayRef>

Return a sparse child by its variant index.

fn child_by_type_id(&self, type_id: u8) -> Option<&ArrayRef>

Return a sparse child selected by a data-level type ID.

fn child_by_name_opt(&self, name: impl AsRef<str>) -> Option<&ArrayRef>

Return a sparse child selected by its variant name, if present.

fn child_by_name(&self, name: impl AsRef<str>) -> VortexResult<&ArrayRef>

Return a sparse child selected by its variant name.

Dyn Compatibility

This trait is not dyn compatible.

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