Struct GenerationPeriod 

pub struct GenerationPeriod {
    pub index: usize,
    pub label: String,
    pub start_date: NaiveDate,
    pub end_date: NaiveDate,
    pub months: u32,
}

A single period within a generation run.

The unified pipeline decomposes the total requested time span into fiscal-year-aligned periods. Each period is generated independently with its own RNG seed derived from the master seed.

Named GenerationPeriod to avoid collision with the accounting-level FiscalPeriod in period_close.

Fields

index: usize

Zero-based index of this period in the run.

label: String

Human-readable label, e.g. “FY2024” or “FY2024-H1”.

start_date: NaiveDate

First calendar date of the period (inclusive).

end_date: NaiveDate

Last calendar date of the period (inclusive).

months: u32

Number of months covered by this period.

Implementations

impl GenerationPeriod

pub fn compute_periods( start_date: NaiveDate, total_months: u32, fiscal_year_months: u32, ) -> Vec<GenerationPeriod>

Decompose a total generation span into fiscal-year-aligned periods.

Arguments

• start_date — first day of the generation window
• total_months — total months requested (e.g. 36 for 3 years)
• fiscal_year_months — months per fiscal year (typically 12)

Returns

A Vec<GenerationPeriod> covering the entire span. The last period may be shorter than fiscal_year_months if total_months is not evenly divisible.

Trait Implementations

impl Clone for GenerationPeriod

fn clone(&self) -> GenerationPeriod

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GenerationPeriod

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GenerationPeriod

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for GenerationPeriod

fn eq(&self, other: &GenerationPeriod) -> 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.

impl Serialize for GenerationPeriod

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
