Expand description

A vertex in a directed acyclic graph that represents a diff.

Each vertex represents two pointers: one to the next unmatched LHS syntax, and one to the next unmatched RHS syntax.

For example, suppose we have X A on the LHS and A on the RHS. Our start vertex looks like this.

LHS: X A     RHS: A
     ^            ^

From this vertex, we could take Edge::NovelAtomLHS, bringing us to this vertex.

LHS: X A     RHS: A
       ^          ^

Alternatively, we could take the Edge::NovelAtomRHS, bringing us to this vertex.

LHS: X A     RHS: A
     ^              ^
