Enum IztroError 

#[non_exhaustive]
pub enum IztroError {
    InvalidDate(String),
    InvalidTimeIndex(u8),
    Internal(String),
}

排盘与运限入口的参数错误。

入口函数对全部外部输入做前置校验并以本类型报错，库内部不因非法参数 panic。这对 wasm 目标尤为关键：wasm 下 panic 即 abort（trap），且每次 trap 都会永久损耗模块实例的栈空间，累积后连合法调用也会失败。

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidDate(String)

日期字符串非法：格式不是 “YYYY-M-D”、该日期不存在， 或超出支持范围（公历 1583-9999 年）。

InvalidTimeIndex(u8)

时辰索引超出 0-12（0=早子时，12=晚子时）。

Internal(String)

依赖的历法库未能给出本应存在的干支或星座取值。 属于库内部缺陷而非调用方过错，以错误返回而非 panic—— wasm 上 panic 会 trap 并损耗实例栈空间。
