Struct Tree

pub struct Tree<T> { /* private fields */ }

The syntax tree struct.

Implementations

impl<T> Tree<T>

where T: Eq + Hash,

pub fn new(string: &str, listener: Option<Listener<T>>) -> Tree<T>

Create new tree.

pub fn set(&mut self, start_idx: usize, end_idx: usize, info: T)

Set syntax/format info for the passed range. The range is the passed start index (inclusive) to the passed end index (exclusive).

pub fn unset(&mut self, start_idx: usize, end_idx: usize, info: T)

Unset the passed syntax/format info for the passed range. The range is the passed start index (inclusive) to the passed end index (exclusive).

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 length(&self) -> usize

Get the length of the underlying text.

pub fn remove(&mut self, idx: usize, count: usize)

Remove a count of characters from the underlying text starting at idx.

pub fn pop(&mut self)

Pop a char from the underlying text.

pub fn clear(&mut self, keep_formats: bool)

Clear the underlying text. Specify whether you want the tree to keep the formats on the root node.

pub fn get_root(&self) -> &Node<T>

Get the root 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.

Trait Implementations

impl<T> Debug for Tree<T>

where T: Ord + Hash + Debug,

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

Formats the value using the given formatter.
