Struct dinotree::tree::Vistr

pub struct Vistr<'a, T: HasAabb> { /* fields omitted */ }

Tree Iterator that returns a reference to each node.

Methods

impl<'a, T: HasAabbMut> Vistr<'a, T>

pub fn create_wrap(&self) -> Vistr<T>

It is safe to borrow the iterator and then produce mutable references from that as long as by the time the borrow ends, all the produced references also go away.

pub fn height(&self) -> usize

Trait Implementations

impl<'a, T: HasAabbMut + 'a> Visitor for Vistr<'a, T>

type Item = NodeRef<'a, T>

The common item produced for both leafs and non leafs.

fn next(self) -> (Self::Item, Option<[Self; 2]>)

Consume this visitor, and produce the element it was pointing to along with it's children visitors.

fn level_remaining_hint(&self) -> (usize, Option<usize>)

Return the levels remaining including the one that will be produced by consuming this iterator. So if you first made this object from the root for a tree of size 5, it should return 5. Think of is as height-depth. This is used to make good allocations when doing dfs and bfs. Defaults to (0,None)

fn dfs_preorder(self, func: impl FnMut(Self::Item))

Calls the closure in dfs preorder (root,left,right). Takes advantage of the callstack to do dfs.

fn with_depth(self, start_depth: Depth) -> LevelIter<Self>

Iterator Adapter to also produce the depth each iteration.

fn zip<F>(self, f: F) -> Zip<Self, F> where
    F: Visitor, 

Combine two tree visitors.

fn map<B, F>(self, func: F) -> Map<Self, F> where
    F: Fn(Self::Item) -> B, 

Map iterator adapter

fn take(self, num: usize) -> Take<Self>

Only produce children up to num.

fn flip(self) -> Flip<Self>

Flips left and right children.

Important traits for DfsPreOrderIter<C>

impl<C> Iterator for DfsPreOrderIter<C> where
    C: Visitor,  type Item = <C as Visitor>::Item;

fn dfs_preorder_iter(self) -> DfsPreOrderIter<Self>

Provides a dfs preorder iterator. Unlike the callback version, This one relies on dynamic allocation for its stack.

Important traits for DfsInOrderIter<C>

impl<C> Iterator for DfsInOrderIter<C> where
    C: Visitor,  type Item = <C as Visitor>::Item;

fn dfs_inorder_iter(self) -> DfsInOrderIter<Self>

fn dfs_inorder<impl FnMut(Self::Item)>(self, func: impl FnMut(Self::Item)) where
    impl FnMut(Self::Item): FnMut(Self::Item), 

Calls the closure in dfs preorder (left,right,root). Takes advantage of the callstack to do dfs.

fn dfs_postorder<impl FnMut(Self::Item)>(self, func: impl FnMut(Self::Item)) where
    impl FnMut(Self::Item): FnMut(Self::Item), 

Calls the closure in dfs preorder (left,right,root). Takes advantage of the callstack to do dfs.
