Enum VisitRecord

Source

enum VisitRecord<'n, N>where
    N: NormalizeEq,{
    EnterMark(usize),
    NodeItem(Identifier<'n, N>, bool),
}

Expand description

Record item that used when traversing a TreeNode tree.

Variants§

§

EnterMark(usize)

Marks the beginning of TreeNode. It contains:

The post-order index assigned during the first, visiting traversal.

§

NodeItem(Identifier<'n, N>, bool)

Marks an accumulated subtree. It contains:

The accumulated identifier of a subtree.
A accumulated boolean flag if the subtree is valid for CSE. The flag is propagated up from children to parent. (E.g. volatile expressions are not valid and can’t be extracted, but non-volatile children of volatile expressions can be extracted.)
