Struct Micros 

pub struct Micros(pub i64);

Exact decimal stored as an integer count of millionths (10^-6).

CSV amounts and quantities are parsed from decimal text. Nothing in this type uses floating point. Half-up rounding happens only in the display helpers.

Tuple Fields

0: i64

Implementations

impl Micros

pub const ZERO: Self

pub const SCALE: i64 = 1_000_000

1.0 = 1_000_000.

pub fn parse(raw: &str) -> Result<Self, DecimalError>

Parse [-+]digits[.digits][e[-+]digits].

A value that is not an exact multiple of 10^-6 is TooManyDecimals. Trailing zeros are kept only when the value still fits in 6 decimal places (1.2300000 is 1.23; 1.2345678 is rejected).

pub fn to_decimal_string(self) -> String

44.232000. Always 6 digits after the decimal point.

pub fn format_cents(self) -> String

Half-up, away from zero, to cents. Display only.

pub fn format_quantity(self) -> String

Up to 3 decimal places, half-up, trailing zeros removed. Used for minutes.

pub fn whole_units(self) -> Option<i64>

Whole units when this value has no fractional millionths.

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

None when the sum does not fit in i64 micros, instead of panicking. Use this to add amounts from untrusted input, such as CSV rows.

Micros deliberately has no Add, AddAssign or Sum impl: every sum must choose between this checked form and an explicit saturating one, so no + on money can panic on overflow.
