Expand description

Concrete syntax tree. 1つの CST は構文規則、テキストの範囲、子要素からなり、全体として木構造をなす。

Fields

rule: Rule

構文規則。

span: Spaninner: Vec<Cst>

Implementations

新たな CST を作成する。

与えられたルールの Cst を再帰的に抽出する。

自分の子のうち、与えられた pos を含むものを返す。

与えられた pos を含む Pair を再帰的に探索する。 範囲が小さいものから順に返す。

自分の Cst の内部で、 child の親となる Cst (child の scope を内包する最小の Cst)を探し、あればそれを返す。

自身及び子要素の Cst を羅列する。

終端要素の Span を返す。ここでいう終端要素とは、 自身の Cst の span には含まれているが、子の span には含まれていない範囲。
