Struct Node 

pub struct Node {
    pub role: Role,
    pub parent: Option<NodeId>,
    pub first_child: Option<NodeId>,
    pub last_child: Option<NodeId>,
    pub next_sibling: Option<NodeId>,
    pub style: StyleId,
    pub text: TextRange,
}

A node in the IR tree.

Fields

role: Role

Semantic role.

parent: Option<NodeId>

Parent node (None for root).

first_child: Option<NodeId>

First child node.

last_child: Option<NodeId>

Last child node. Maintained by Chapter::append_child so appends are O(1); it is only guaranteed accurate during tree construction. The optimizer passes rewire siblings directly and do not append afterward, so they intentionally leave this field alone.

next_sibling: Option<NodeId>

Next sibling node.

style: StyleId

Style identifier.

text: TextRange

Text content range (only for Text nodes).

Implementations

impl Node

pub fn new(role: Role) -> Self

pub fn text(range: TextRange) -> Self

Create a text node with the given range.

Trait Implementations

impl Clone for Node

fn clone(&self) -> Node

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Node

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
