    index: Cell<Option<u32>>,
    pub(crate) old_parent: Option<&'a Node>,
    prev_sibling: Option<&'a Node>,
    pub(crate) next_sibling: Option<&'a Node>,
}

Fields

index: Cell<Option<u32>>

The index of the inclusive ancestor that was moved.

old_parent: Option<&'a Node>

prev_sibling: Option<&'a Node>

The previous sibling of the inclusive ancestor that was moved.

next_sibling: Option<&'a Node>

The next sibling of the inclusive ancestor that was moved.

Implementations
