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

Variants

Fields

item: VOffset<T, ItemVTable, AllowPin>

byte offset where we can find the item (from the *ComponentImpl)

children_count: u32

number of children

children_index: u32

Static item

DynamicTree

Fields

index: usize

the index which is passed in the visit_dynamic callback.

parent_index: u32

The index of the parent item (not valid for the root)
