Struct PrimitiveOutputBuilder

pub(super) struct PrimitiveOutputBuilder<'a, T: ArrowPrimitiveVariant> {
    path: VariantPath<'a>,
    as_type: FieldRef,
    cast_options: CastOptions<'a>,
    _phantom: PhantomData<T>,
}

Outputs Primitive arrays

Fields

path: VariantPath<'a>

What path to extract

as_type: FieldRef

Returned output type

cast_options: CastOptions<'a>

Controls the casting behavior (e.g. error vs substituting null on cast error).

_phantom: PhantomData<T>

Phantom data for the primitive type

Trait Implementations

impl<'a, T: ArrowPrimitiveVariant> OutputBuilder for PrimitiveOutputBuilder<'a, T>

fn partially_shredded( &self, variant_array: &VariantArray, _metadata: &BinaryViewArray, _value_field: &BinaryViewArray, typed_value: &ArrayRef, ) -> Result<ArrayRef>

fn typed( &self, _variant_array: &VariantArray, _metadata: &BinaryViewArray, typed_value: &ArrayRef, ) -> Result<ArrayRef>

output for a perfectly shredded variant array

fn unshredded( &self, _variant_array: &VariantArray, _metadata: &BinaryViewArray, _value_field: &BinaryViewArray, ) -> Result<ArrayRef>

write out an unshredded variant array
