Struct DecimalValue 

pub struct DecimalValue { /* private fields */ }

Runtime representation of a Decimal128 value.

Implementations

impl DecimalValue

pub fn new(value: i128, scale: i8) -> Result<Self, DecimalError>

Create a decimal from its raw parts, validating precision bounds.

pub fn from_i64(value: i64) -> Self

Construct a decimal from integer value with zero scale.

pub fn raw_value(self) -> i128

Return the scaled integer backing this decimal.

pub fn scale(self) -> i8

Return the scale (number of fractional digits).

pub fn precision(self) -> u8

Return the decimal precision (total digit count).

pub fn to_f64(self) -> f64

Convert the decimal into an f64 (lossy for high precision inputs).

Trait Implementations

impl Clone for DecimalValue

fn clone(&self) -> DecimalValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DecimalValue

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

Formats the value using the given formatter.

impl Display for DecimalValue

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

Formats the value using the given formatter.

impl From<DecimalValue> for Literal

fn from(v: DecimalValue) -> Self

Converts to this type from the input type.

impl FromStr for DecimalValue

type Err = DecimalError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for DecimalValue

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 Ord for DecimalValue

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for DecimalValue

fn eq(&self, other: &DecimalValue) -> 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 DecimalValue

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.
