Struct SeasonDefinition 

pub struct SeasonDefinition {
    pub id: usize,
    pub label: String,
    pub month_start: u32,
    pub day_start: Option<u32>,
    pub month_end: Option<u32>,
    pub day_end: Option<u32>,
}

A single season entry mapping a season ID to a calendar period.

Season definitions are required when deriving AR parameters from inflow history — the season determines how history values are aggregated into seasonal means and standard deviations.

Source: stages.json season_definitions.seasons[]. See Input Scenarios §1.1.

Fields

id: usize

Season index (0-based). For monthly cycles: 0 = January, …, 11 = December. For weekly cycles: 0-51 (ISO week numbers).

label: String

Human-readable label (e.g., “January”, “Q1”, “Wet Season”).

month_start: u32

Calendar month where this season starts (1-12). For monthly cycle_type, this uniquely identifies the month.

day_start: Option<u32>

Calendar day where this season starts (1-31). Only used when cycle_type is Custom. Default: 1.

month_end: Option<u32>

Calendar month where this season ends (1-12). Only used when cycle_type is Custom.

day_end: Option<u32>

Calendar day where this season ends (1-31). Only used when cycle_type is Custom.

Trait Implementations

impl Clone for SeasonDefinition

fn clone(&self) -> SeasonDefinition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SeasonDefinition

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

Formats the value using the given formatter.

impl PartialEq for SeasonDefinition

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