Struct SettlementPeriod 

pub struct SettlementPeriod { /* private fields */ }

The delivery period a settlement covers.

A validated pair rather than two loose dates. Every input struct previously carried period_from and period_to independently, and every calculation re-checked their ordering — five copies of the same guard, each able to be forgotten. Constructing this type is the check.

Both bounds are inclusive: a monthly period runs from the 1st to the last day of the month, matching how Netzentgelte are published and billed.

Implementations

impl SettlementPeriod

pub fn new(from: Date, to: Date) -> Result<Self, BillingError>

Build a period.

Errors

Returns crate::error::BillingError::InvalidInput when from is after to. A zero-length period (from == to) is a valid single day.

pub const fn from(&self) -> Date

Start of the period, inclusive.

pub const fn to(&self) -> Date

End of the period, inclusive.

pub fn days(&self) -> i64

Number of days covered, both bounds inclusive.
