pub struct NodeInfo {
    pub loc: SourceLocation,
    pub macro_expansion: Option<Box<MacroExpansionInfo>>,
}
Expand description

ASTノードの共通メタデータ

ソース位置とオプションのマクロ展開情報を保持する。 Phase 5 で各ASTノードの loc: SourceLocationinfo: NodeInfo に置き換える。

Fields§

§loc: SourceLocation

ソース位置

§macro_expansion: Option<Box<MacroExpansionInfo>>

マクロ展開情報(マクロ展開由来の場合のみ Some)
