Struct ChartCalculationConfig 

pub struct ChartCalculationConfig {
    pub solar_time: SolarTimePolicy,
    pub year_boundary: YearBoundary,
    pub leap_month_boundary: LeapMonthBoundary,
    pub nominal_age_boundary: NominalAgeBoundary,
}

The input calculation policy applied before chart generation.

This is a separate axis from the algorithm family and the chart plane. With the default policy, the clock-time API derives the 时辰 from the supplied clock time and produces the same chart as the legacy time-index API for the same 时辰.

year_boundary and leap_month_boundary affect natal chart generation; nominal_age_boundary affects runtime/horoscope nominal-age resolution only. All default to the values that preserve existing iztro-rs behaviour and fixtures.

Fields

solar_time: SolarTimePolicy

Policy controlling how birth clock time becomes a 时辰.

year_boundary: YearBoundary

年分界 policy controlling the effective cyclic birth year.

leap_month_boundary: LeapMonthBoundary

闰月分界 policy controlling leap-month month attribution.

nominal_age_boundary: NominalAgeBoundary

虚岁分界 policy controlling runtime nominal-age increments.

Implementations

impl ChartCalculationConfig

pub const fn new(solar_time: SolarTimePolicy) -> Self

Creates a calculation config from an explicit solar-time policy.

The boundary policies use their defaults (YearBoundary::ChineseNewYearEve, LeapMonthBoundary::MidMonth, NominalAgeBoundary::NaturalYear).

pub const fn clock_time() -> Self

Creates the default clock-time calculation config.

pub const fn apparent_solar_time(config: ApparentSolarTimeConfig) -> Self

Creates an apparent-solar-time calculation config.

pub const fn with_year_boundary(self, year_boundary: YearBoundary) -> Self

Returns a copy with the 年分界 policy replaced.

pub const fn with_leap_month_boundary( self, leap_month_boundary: LeapMonthBoundary, ) -> Self

Returns a copy with the 闰月分界 policy replaced.

pub const fn with_nominal_age_boundary( self, nominal_age_boundary: NominalAgeBoundary, ) -> Self

Returns a copy with the 虚岁分界 policy replaced.

Trait Implementations

impl Clone for ChartCalculationConfig

fn clone(&self) -> ChartCalculationConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ChartCalculationConfig

impl Debug for ChartCalculationConfig

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

Formats the value using the given formatter.

impl Default for ChartCalculationConfig

fn default() -> ChartCalculationConfig

Returns the “default value” for a type.

impl PartialEq for ChartCalculationConfig

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