Struct viewbuilder::tree::Tree

pub struct Tree { /* private fields */ }

Tree of user interface nodes.

Implementations

impl Tree

pub fn iter(&self, root: NodeKey) -> Iter<'_>

pub fn iter_mut(&mut self, root: NodeKey) -> IterMut<'_>

pub fn target(&self, root: NodeKey, point: Point) -> Option<NodeKey>

Get the target under the current point.

This function will return Some with a key to the node at point with the highest layout order. Otherwise None is returned.

pub fn display(&self, root: NodeKey) -> String

Display the tree as a string starting from a root key.

Trait Implementations

impl Default for Tree

fn default() -> Tree

impl Index<NodeKey> for Tree

type Output = Node

The returned type after indexing.

fn index(&self, index: NodeKey) -> &Self::Output

Performs the indexing (container[index]) operation.

impl IndexMut<NodeKey> for Tree

fn index_mut(&mut self, index: NodeKey) -> &mut Self::Output

Performs the mutable indexing (container[index]) operation.
