Struct DecimalScalar

pub struct DecimalScalar<'a> { /* private fields */ }

A scalar value representing a decimal number with fixed precision and scale.

Implementations

impl<'a> DecimalScalar<'a>

pub fn try_new(dtype: &'a DType, value: &ScalarValue) -> VortexResult<Self>

Creates a new decimal scalar from a data type and scalar value.

Errors

Returns an error if the data type is not a decimal type.

pub fn dtype(&self) -> &'a DType

Returns the data type of this decimal scalar.

pub fn decimal_value(&self) -> &Option<DecimalValue>

Returns the decimal value, or None if null.

Trait Implementations

impl<'a> Clone for DecimalScalar<'a>

fn clone(&self) -> DecimalScalar<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for DecimalScalar<'a>

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

Formats the value using the given formatter.

impl Display for DecimalScalar<'_>

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

Formats the value using the given formatter.

impl From<DecimalScalar<'_>> for Scalar

fn from(decimal_scalar: DecimalScalar<'_>) -> Self

Converts to this type from the input type.

impl<'a> Hash for DecimalScalar<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DecimalScalar<'_>

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for DecimalScalar<'_>

Ord is not implemented since it’s undefined for different PTypes

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
