Enum PropertyLayerData 

#[non_exhaustive]
pub enum PropertyLayerData<I>
where
    I: PropertyIndex,
{
    Dense {
        values: ArrayRef,
    },
    Sparse {
        indices: Arc<PrimitiveArray<I::ArrowType>>,
        values: ArrayRef,
        default: Option<ArrayRef>,
    },
}

Data backing one property layer.

Performance

Cloning is O(1) because Arrow arrays are reference-counted.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Dense

Dense Arrow array with one slot per ID index.

Fields

values: ArrayRef

Dense values.

Sparse

Sparse Arrow array keyed by explicit indexes.

Fields

indices: Arc<PrimitiveArray<I::ArrowType>>

Strictly ascending sparse indexes.

values: ArrayRef

Values aligned with indices.

default: Option<ArrayRef>

Optional Arrow scalar default encoded as a length-one array.
