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
• TraversalOrder

Traits

• ItemTree
  A ItemTree is representing an unit that is allocated together Note: Was generated from the #[vtable] macro on ItemTreeVTable
• 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.
• unregister_item_tree
  Free the backend graphics resources allocated by the ItemTree’s items.
• visit_item_tree
  Visit the children within an array of ItemTreeNode
• visit_items
  Visit each items recursively

Type Aliases

• ItemTreeRc
  Type alias to the commonly used VRc<ItemTreeVTable, Dyn>>
• ItemTreeRef
  Alias for vtable::VRef<ItemTreeVTable> which represent a pointer to a dyn ItemTree with the associated vtable
• ItemTreeRefPin
  Type alias to the commonly used Pin<VRef<ItemTreeVTable>>>
• ItemTreeWeak
  Type alias to the commonly used VWeak<ItemTreeVTable, Dyn>>
• ItemVisitorRefMut
  Type alias to vtable::VRefMut<ItemVisitorVTable>
