示例2: nodeCanBeReused

bool SyntaxParsingCache::nodeCanBeReused(const Syntax &Node, size_t NodeStart,
                                         size_t Position,
                                         SyntaxKind Kind) const {

  // node's absolute position, but make sure the values match in an assertion
  // build

    return false;
  if (Node.getKind() != Kind)
    return false;

  // Node can also not be reused if an edit has been made in the next token's
  // text, e.g. because `private struct Foo {}` parses as a CodeBlockItem with a
  // StructDecl inside and `private struc Foo {}` parses as two CodeBlockItems
  // one for `private` and one for `struc Foo {}`
  size_t NextLeafNodeLength = 0;
  if (auto NextNode = Node.getData().getNextNode()) {
    auto NextLeafNode = NextNode->getFirstToken();

    }
  }

  auto NodeEnd = NodeStart + Node.getTextLength();
  for (auto Edit : Edits) {
    // Check if this node or the trivia of the next node has been edited. If it
    // has, we cannot reuse it.
    if (Edit.intersectsOrTouchesRange(NodeStart, NodeEnd + NextLeafNodeLength))
