Trait Implementations

impl ArrowPrimitiveType for Decimal256Type

const DATA_TYPE: DataType = <Self as DecimalType>::DEFAULT_TYPE

the corresponding Arrow data type of this primitive type.

type Native = i256

fn default_value() -> Self::Native

Returns a default value of this primitive type.

impl Debug for Decimal256Type

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl DecimalType for Decimal256Type

const BYTE_LENGTH: usize = 32

Width of the type

const MAX_PRECISION: u8 = DECIMAL256_MAX_PRECISION

const MAX_SCALE: i8 = DECIMAL256_MAX_SCALE

Maximum no of digits after the decimal point (note the scale can be negative)

const MAX_FOR_EACH_PRECISION: &'static [i256]

The maximum value for each precision in 0..=MAX_PRECISION: [0, 9, 99, …]

const TYPE_CONSTRUCTOR: fn(u8, i8) -> DataType = DataType::Decimal256

fn to create its [DataType]

const DEFAULT_TYPE: DataType

Default values for [DataType]

const PREFIX: &'static str = "Decimal256"

“Decimal32”, “Decimal64”, “Decimal128” or “Decimal256”, for use in error messages

fn format_decimal(value: Self::Native, precision: u8, scale: i8) -> String
