A renderer-neutral, hierarchical drill-down selection for the bottom panel.

A renderer (TUI/GUI) reports which bottom-panel cell the user chose as an index path (大限 → 流年 → 流月 → 流日 → 流时); core resolves the indices to concrete lunar/solar coordinates and prepares the matching StaticChartViewSnapshot. Each deeper variant carries its ancestors’ indices. The renderer never derives the overlay, the lunar labels, or the month/day validity itself.

Indices: year_index 0..=9 (within the 大限’s 10 years); month_index 0..=11 (lunar month 正月..腊月); day_index 0..=29 (lunar day 初一..三十); hour_index 0..=11 (double-hour 子..亥).

Variants

Natal

本命 — the natal slice with no temporal overlay.

PreDecadal

限前 — the span before the first 大限. Carries no overlay; natal base.

Decadal

大限 — the selected decadal period; enables the 流年 row.

Fields

decadal_index: usize

Zero-based index into the decadal frame periods.

Yearly

流年/小限 — a year within the selected 大限; enables the 流月 row.

Fields

decadal_index: usize

Selected decadal period index.

year_index: u8

Zero-based year within the period (0..=9).

Monthly

流月 — a lunar month of the selected 流年; enables the 流日 row.

Fields

decadal_index: usize

Selected decadal period index.

year_index: u8

Selected year within the period (0..=9).

month_index: u8

Zero-based lunar month (0..=11 -> 正月..腊月).

Daily

流日 — a lunar day of the selected 流月; enables the 流时 row.

Fields

decadal_index: usize

Selected decadal period index.

year_index: u8

Selected year within the period (0..=9).

month_index: u8

Selected lunar month (0..=11).

day_index: u8

Zero-based lunar day (0..=29 -> 初一..三十).

Hourly

流时 — a double-hour of the selected 流日.

Fields

decadal_index: usize

Selected decadal period index.

year_index: u8

Selected year within the period (0..=9).

month_index: u8

Selected lunar month (0..=11).

day_index: u8

Selected lunar day (0..=29).

hour_index: u8

Zero-based double-hour (0..=11 -> 子..亥).

Implementations

impl StaticTemporalNavigationSelection

pub const fn decadal_index(&self) -> Option<usize>

The selected decadal period index, if the path reaches 大限.

pub const fn year_index(&self) -> Option<u8>

The selected year index, if the path reaches 流年.

pub const fn month_index(&self) -> Option<u8>

The selected lunar-month index, if the path reaches 流月.

pub const fn day_index(&self) -> Option<u8>

The selected lunar-day index, if the path reaches 流日.

pub const fn hour_index(&self) -> Option<u8>

The selected double-hour index, if the path reaches 流时.

Trait Implementations

impl Clone for StaticTemporalNavigationSelection

fn clone(&self) -> StaticTemporalNavigationSelection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for StaticTemporalNavigationSelection

impl Debug for StaticTemporalNavigationSelection

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

Formats the value using the given formatter.

impl Default for StaticTemporalNavigationSelection

fn default() -> StaticTemporalNavigationSelection

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for StaticTemporalNavigationSelection

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for StaticTemporalNavigationSelection

impl Hash for StaticTemporalNavigationSelection

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for StaticTemporalNavigationSelection

fn eq(&self, other: &StaticTemporalNavigationSelection) -> 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 StaticTemporalNavigationSelection

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
