fn is_constant( &self, _array: &ListArray, _opts: &IsConstantOpts, ) -> VortexResult<Option<bool>>

Preconditions

impl MaskFn<&ListArray> for ListEncoding

fn mask(&self, array: &ListArray, mask: Mask) -> VortexResult<ArrayRef>

Replace masked values with null in array.

impl MinMaxFn<&ListArray> for ListEncoding
