Struct arrow2_convert::field::I128

pub struct I128<const PRECISION: usize, const SCALE: usize> {}

Maps a rust i128 to an Arrow Decimal where precision and scale are required.

Trait Implementations

impl<const PRECISION: usize, const SCALE: usize> ArrowDeserialize for I128<PRECISION, SCALE>

type ArrayType = PrimitiveArray<i128>

The arrow2::Array type corresponding to this field

fn arrow_deserialize<'a>(v: Option<&i128>) -> Option<i128>

Deserialize this field from arrow

impl<const PRECISION: usize, const SCALE: usize> ArrowField for I128<PRECISION, SCALE>

type Type = i128

This should be Self except when implementing large offset and fixed placeholder types. For the later, it should refer to the actual type. For example when the placeholder type is LargeString, this should be String.

fn data_type() -> DataType

The DataType

impl<const PRECISION: usize, const SCALE: usize> ArrowSerialize for I128<PRECISION, SCALE>

type MutableArrayType = MutablePrimitiveArray<i128>

The arrow2::array::MutableArray that holds this value

fn new_array() -> Self::MutableArrayType

Create a new mutable array

fn arrow_serialize(v: &i128, array: &mut Self::MutableArrayType) -> Result<()>

Serialize this field to arrow
