/* /*
LOD Data contains different Entries in different Vecs, every entry has a "pointer" to it's child start. Terminology:
This is the structure to store a region and all subscribed information - Layer: the layer of the LoDTree, a tree can have n layers, every layer contains their child layer, except for the last one.
Each layer contains a level, a number from 15-0. the level of each child must be lower than the parents layer!
- Detail: Each Layer contains information about that layer, here called Detail. This is the usable information we want to store in the LoDTree
- LodPos: A LodPos marks a specific position inside the LoDTree, but not their layer.
Each Detail has a LodPos. Multiple Details can exist at the same LodPos on different layers!
- Index: This refers to the actually storage for the index for the next layer (often a u16,u32).
The Index is used to find the child in a spare storage.
- Key: always refers to the storage of a LAYER. Any keyword with KEY is either of type usize or LodPos.
traits:
- Layer: Every layer must implement this. KEY is the storage Type and either usize/LodPos. Layer is also defined here.
- ParentLayer: Is a Layer that contains a CHILD layer and some const functions based on their const properties
- IndexStore: Every layer must implement this for their Layer::KEY and INDEX is often u16/u32.
The index is accessed by this layer to get the corresponding child.
Every Indexstore is a ParentLayer.
- DetailStore: Every layer must implement this for their KEY.
This is used to store the actual DETAIL of every layer.
!!Calculations will be implemented on these 2 Stores, rather than the actual structs to reduce duplciate coding!!
- ToOptionUsize: to store INDEX in z16/u32 efficiently and move up to usize on calculation
- Traversable: trait is used to get child layer and child Index for a concrete position.
- Materializeable: trait is used to actually return a Detail for a concrete position.
Actual structs regarding of position in the chain. They represent the Layers and contain the Details, they implement (some of) the 2 Store traits
Naming Scheme is <Own Detail Type>[Nest]Layer
- VecLayer: KEY=usize, stores in Vec, leaf layer
- HashLayer:KEY=LodPos, stores in Vec, leaf layer
- VecNestLayer: KEY=usize, stores in Vec, has childs
- HashNestLayer: KEY=LodPos, stores in Vec, has childs
Result Structs:
- HashIter/VecIter: Is used to access a layer meta information or Detail via LoDTree.trav().get().get().get().mat().
When LoDTree.trav() returns a HashIter.
It keeps information to next layer to not recalculate it

Terminology:
- Layer: the layer of the LoDTree, a tree can have n layers, every layer contains their child layer, except for the last one.
Each layer contains a level, a number from 15-0. the level of each child must be lower than the parents layer!
- Detail: Each Layer contains information about that layer, here called Detail. This is the usable information we want to store in the LoDTree
- LodPos: A LodPos marks a specific position inside the LoDTree, but not their layer.
Each Detail has a LodPos. Multiple Details can exist at the same LodPos on different layers!
- Index: This refers to the actually storage for the index for the next layer (often a u16,u32).
The Index is used to find the child in a spare storage.
- Key: always refers to the storage of a LAYER. Any keyword with KEY is either of type usize or LodPos.
traits:
- Layer: Every layer must implement this. KEY is the storage Type and either usize/LodPos. Layer is also defined here.
- ParentLayer: Is a Layer that contains a CHILD layer and some const functions based on their const properties
- IndexStore: Every layer must implement this for their Layer::KEY and INDEX is often u16/u32.
The index is accessed by this layer to get the corresponding child.
Every Indexstore is a ParentLayer.
- DetailStore: Every layer must implement this for their KEY.
This is used to store the actual DETAIL of every layer.
!!Calculations will be implemented on these 2 Stores, rather than the actual structs to reduce duplciate coding!!
- ToOptionUsize: to store INDEX in z16/u32 efficiently and move up to usize on calculation
- Traversable: trait is used to get child layer and child Index for a concrete position.
- Materializeable: trait is used to actually return a Detail for a concrete position.
Actual structs regarding of position in the chain. They represent the Layers and contain the Details, they implement (some of) the 2 Store traits
Naming Scheme is <Own Detail Type>[Nest]Layer
- VecLayer: KEY=usize, stores in Vec, leaf layer
- HashLayer:KEY=LodPos, stores in Vec, leaf layer
- VecNestLayer: KEY=usize, stores in Vec, has childs
- HashNestLayer: KEY=LodPos, stores in Vec, has childs
Result Structs:
- HashIter/VecIter: Is used to access a layer meta information or Detail via LoDTree.trav().get().get().get().mat().
When LoDTree.trav() returns a HashIter.
It keeps information to next layer to not recalculate it
