[−][src]Struct xtree::Cursor

pub struct Cursor<'a, T> { /* fields omitted */ }

A immutable Cursor can freely visit node in tree

Implementations

impl<'a, T> Cursor<'a, T>[src]

pub fn move_child(&mut self, at: usize)[src]

Move this cursor to the specified child

Panics

Panics if 'at' >= children_count()

pub fn move_parent(&mut self)[src]

move this cursor to its parent. Do nothing if it is already in the root node.

pub fn move_root(&mut self)[src]

Move this cursor to its root. Do nothing if it is already in the root node.

pub fn current(&self) -> &'a T[src]

Return the reference to the current

pub fn children_count(&self) -> usize[src]

Get the count of children in current node

pub fn children(&self) -> ChildrenIter<'a, T>ⓘ

Notable traits for ChildrenIter<'a, T>

impl<'a, T> Iterator for ChildrenIter<'a, T> type Item = &'a T;
[src]

Get a immutable children iterator

pub fn is_root(&self) -> bool[src]

Return true if current node is the root

pub fn is_leaf(&self) -> bool[src]

Return true if current node is a leaf
