Module item_tree 

This module contains the ItemTree and code that helps navigating it

Macros

ItemTreeVTable_static

Instantiate a static ItemTreeVTable for a given type and implements vtable::HasStaticVTable<ItemTreeVTable> for it.

ItemVisitorVTable_static

Instantiate a static ItemVisitorVTable for a given type and implements vtable::HasStaticVTable<ItemVisitorVTable> for it.

Structs

IndexRange

A range of indices

ItemRc

A ItemRc is holding a reference to a ItemTree containing the item, and the index of this item

ItemTreeNodeArray

The ItemTreeNodeArray provides tree walking code for the physical ItemTree stored in a ItemTree without stitching any inter-ItemTree links together!

ItemTreeTO

Invariant, same as vtable::Inner: vtable and ptr has to be valid and ptr an instance matching the vtable

ItemTreeVTable

A ItemTree is representing an unit that is allocated together

ItemVisitorTO

Invariant, same as vtable::Inner: vtable and ptr has to be valid and ptr an instance matching the vtable

ItemVisitorVTable

Object to be passed in visit_item_children method of the ItemTree.

ItemWeak

A Weak reference to an item that can be constructed from an ItemRc.

VisitChildrenResult

The return value of the ItemTree::visit_children_item function

Enums

ItemTreeNode

The item tree is an array of ItemTreeNode representing a static tree of items within a ItemTree.

ItemVisitorResult

ParentItemTraversalMode

TraversalOrder

Traits

ItemTree

ItemVisitor

Object to be passed in visit_item_children method of the ItemTree. Note: Was generated from the #[vtable] macro on ItemVisitorVTable

Functions

register_item_tree

Call init() on the ItemVTable for each item of the ItemTree.
