Struct MergePair 

pub struct MergePair {
    pub first: Option<NodeRef>,
    pub second: Option<NodeRef>,
}

Either node may be None if only one branch has content at this position.

Fields

first: Option<NodeRef>

The node from the first branch (left).

second: Option<NodeRef>

The node from the second branch (right).
