ReassocOutcome

cure_engine::lang

Enum ReassocOutcome 

Source 
pub enum ReassocOutcome<Id> {
    Neutral,
    Lit(Id, BinOp),
}
Expand description

Lang::reassoc_delta 的合并结果。

Variants§

§

Neutral

合并为中性元（(x+K1)-K1 类）→ 直接替换为 x。

§

Lit(Id, BinOp)

合并后的常量字面量节点 + 建议算符（x op lit；负常量由语言侧 决定用 Sub 正字面量还是 Add 负字面量表达）。
