Struct DecimalValue 

pub struct DecimalValue { /* private fields */ }

An exact base-ten decimal represented as coefficient * 10^-scale.

Implementations

impl DecimalValue

pub fn new(coefficient: i128, scale: u32) -> Result<Self>

Creates a decimal and removes insignificant trailing fractional zeros.

Errors

Returns ErrorKind::InvalidArgument when the normalized scale exceeds MAX_METADATA_DECIMAL_SCALE.

pub const fn coefficient(self) -> i128

Returns the signed base-ten coefficient.

pub const fn scale(self) -> u32

Returns the number of fractional decimal digits.

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 Copy for DecimalValue

impl Debug for DecimalValue

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

Formats the value using the given formatter.

impl Eq for DecimalValue

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 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.
