class FoldingSetNodeIDRef

Declaration

class FoldingSetNodeIDRef { /* full declaration omitted */ };

Description

FoldingSetNodeIDRef - This class describes a reference to an interned FoldingSetNodeID, which can be a useful to store node id data rather than using plain FoldingSetNodeIDs, since the 32-element SmallVector is often much larger than necessary, and the possibility of heap allocation means it requires a non-trivial destructor call.
