Struct InvoiceAmount 

pub struct InvoiceAmount(/* private fields */);

EN 16931 Amount.Type: at most two fraction digits. Never f64. Never rounds.

Implementations

impl InvoiceAmount

pub const ZERO: Self

Zero amount.

pub fn from_minor(cents: i64) -> Self

Integer minor units (cents) as a two-decimal amount.

pub fn try_new(value: Decimal) -> Result<Self, AmountError>

Accepts at most two fraction digits. Refuses excess; never rounds.

pub fn parse(s: &str) -> Result<Self, AmountError>

Parse a decimal string. Excess fraction digits are refused; never rounds.

pub fn raw(self) -> Decimal

Underlying decimal.

pub fn is_zero(self) -> bool

Whether the value is zero.

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

Sum, or None on overflow. Does not saturate.

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

Difference, or None on overflow. Does not saturate.

pub fn abs(self) -> Self

Absolute value.

pub fn checked_sum(amounts: impl IntoIterator<Item = Self>) -> Option<Self>

Sum of amounts, or None on overflow. Does not saturate.

pub fn from_decimal_rounded(value: Decimal) -> Result<Self, AmountError>

Commercial rounding (half away from zero) to two decimals — producer presentation. Validators use crate::arith::xpath_round.
