Required Methods

fn maybe_null_field_by_idx(&self, idx: usize) -> VortexResult<ArrayRef>

Return a field’s array by index, ignoring struct nullability

fn project(&self, projection: &[FieldName]) -> VortexResult<ArrayRef>

Provided Methods

fn names(&self) -> &FieldNames

fn dtypes(&self) -> Vec<DType>

fn nfields(&self) -> usize

fn maybe_null_field_by_name(&self, name: &str) -> VortexResult<ArrayRef>

Return a field’s array by name, ignoring struct nullability
