Struct Decimal 

pub struct Decimal { /* private fields */ }

A checked fixed-scale decimal value.

Implementations

impl Decimal

pub const fn new( spec: DecimalSpec, coefficient: i128, ) -> Result<Self, DecimalError>

Validates and creates a decimal from its type and coefficient.

pub const fn spec(self) -> DecimalSpec

Returns the declared decimal type.

pub const fn coefficient(self) -> i128

Returns the signed fixed-scale coefficient.

pub fn checked_add(self, other: Self) -> Result<Self, DecimalError>

Adds two values of exactly the same decimal type.

pub fn checked_sub(self, other: Self) -> Result<Self, DecimalError>

Subtracts two values of exactly the same decimal type.

pub fn checked_cmp(self, other: Self) -> Result<Ordering, DecimalError>

Compares two values of exactly the same decimal type.

pub fn rescale(self, target: DecimalSpec) -> Result<Self, DecimalError>

Changes the declared scale without rounding or changing the numeric value.
