pub struct Node<T> { /* fields omitted */ }

Methods

impl<T> Node<T>

pub fn new_leaf(text: String, obj: Option<Rc<T>>) -> Node<T>

Create new leaf node.

pub fn new() -> Node<T>

Create new node.

pub fn is_leaf(&self) -> bool

Check whether this node is a

pub fn add_child(&mut self, child: Node<T>)

Add a child to this node.

pub fn text(&self) -> String

Get text the node (or children) is/are holding.

pub fn length(&self) -> usize

Length of the underlying text.

pub fn obj(&self) -> Option<&Rc<T>>

Get the object the node is holding.

pub fn set(
    &mut self,
    start_idx: usize,
    end_idx: usize,
    obj: Rc<T>
) -> Option<Vec<Node<T>>>

Set syntax/format info for the passed range. The range is the passed start index (inclusive) to the passed end index (exclusive). Returns a list of nodes to replace the current one in case that is needed (optional).

pub fn insert(&mut self, idx: usize, ch: char)

Insert a char in the underlying text.

pub fn insert_str(&mut self, idx: usize, string: &str)

Insert a string in the underlying text.

pub fn push(&mut self, ch: char)

Push a char to the underlying text.

pub fn push_str(&mut self, string: &str)

Push a string to the underlying text.

pub fn child_count(&self) -> usize

Get the count of children under this node.

pub fn children(&self) -> &[Node<T>]

Get a slice of all children under this node.

pub fn pre_order_iter(&self) -> PreOrder<T>

Get a depth first pre order iterator.

pub fn leaf_iter(&self) -> impl Iterator<Item = Item<T>>

Get a leaf iterator.

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

Formats the value using the given formatter.
