Constants

TAIYIN_C_LOCAL_SOLAR_CONTACT_COUNT → const int
TAIYIN_C_LUNAR_ECLIPSE_CONTACT_COUNT → const int
TAIYIN_C_OCCULTATION_MAX_VISIBILITY_INTERVALS → const int
TAIYIN_C_OCCULTATION_WHERE_MAX_PATH_POINTS → const int
TAIYIN_C_OCCULTATION_WHERE_MAX_POLYGON_POINTS → const int
TAIYIN_C_SOLAR_BESSELIAN_COEFF_COUNT → const int
TAIYIN_C_SOLAR_ECLIPSE_CONTACT_COUNT → const int
taiyinBaziCapability → const int
taiyinBaziSymbols → const Set<String>: BaZi symbols, verified by package:ephemeris_bazi only when the loaded library advertises the BaZi capability. The symbols do not exist in a build without TAIYIN_BUILD_BAZI_EXTENSION=ON, so they must never be looked up otherwise.
taiyinChineseCalendarCapability → const int
taiyinGanzhiCalendarCapability → const int
taiyinRequiredAbi9Symbols → const Set<String>: Symbols required by the ABI-10 native baseline used by this package.
taiyinSplitTimeCapability → const int
taiyinSupportedAbiVersion → const int
taiyinZiweiCapability → const int
taiyinZiweiSymbols → const Set<String>: Ziwei symbols, verified only when the loaded library advertises the Ziwei capability. The symbols do not exist in a build without TAIYIN_BUILD_ZIWEI_EXTENSION=ON, so they must never be looked up otherwise.

Functions

decodeNativeCallResult(int rawResult) → DecodedCallResult: Decodes an ABI-10 packed call result or a retained legacy status return.
readCalendarDateTime(taiyin_calendar_datetime value) → AstroDateTime: Converts a native calendar struct into an AstroDateTime using the same second rounding the time API applies to reverseJulianDay.
readJulianDate<S extends TimeScale>(taiyin_split_julian_date value) → JulianDate<S>: Reads a split Julian date returned by the C ABI into a JulianDate.
validatedNativeArrayCount(int count, String noun) → int: Validates a native-required element count before allocating the buffer.
validatedNativeResultCount(int count, int capacity) → int: Validates the element count reported by a native array fill against the capacity of the buffer that was passed in.
validateNativeCalendar(AstroDateTime value) → void: Validates fields that can narrow at the native calendar ABI boundary.
validateNativeFinite(double value, String name) → void: Requires a finite floating-point value at an FFI boundary.
validateNativeInt32(int value, String name) → void: Validates a Dart integer before passing it to a native int32_t field.
validateNativeJulianDate<S extends TimeScale>(JulianDate<S> value) → void: Validates fields that can narrow at the native split-JD ABI boundary.
validateNativeSize(int value, String name) → void: Validates a non-negative Dart integer before passing it as native size_t.
validateNativeUint16(int value, String name) → void: Validates a Dart integer before passing it to a native uint16_t field.
validateNativeUint32(int value, String name) → void: Validates a Dart integer before passing it to a native uint32_t field.
validateNativeUint8(int value, String name) → void: Validates a Dart integer before passing it to a native uint8_t field.
validateTaiyinNativeCompatibility({required int abiVersion, required int capabilities}) → void: Validates the native metadata available before any optional symbol lookup.
validateTaiyinRequiredSymbols({required bool providesSymbol(String symbol), Set<String> requiredSymbols = taiyinRequiredAbi9Symbols}) → void: Rejects incomplete ABI-10 builds before generated bindings lazily look up a missing symbol.
writeJulianDate<S extends TimeScale>(Arena arena, JulianDate<S> value) → Pointer<taiyin_split_julian_date>: Marshals a split Julian date into an arena-owned C ABI struct.
writeNativeCalendar(TaiyinBindings bindings, Arena arena, AstroDateTime value) → Pointer<taiyin_calendar_datetime>: Marshals an astronomical calendar value into an arena-owned C ABI struct.
