This snippet will track a unit's inventory.
It won't cache all the items and put them in order by slot number though.
It will however track item raw codes in slots.
Code
Demo
Feel free to commentand/or suggest any additions to the API. (No. Do not ask me to change the API.)
This won't win any benchmarks, but it will cache static data and provide you with wrappers to make your lives a bit easier and your codes a bit more readable.

* UnitInventory
* v2.0.0.0
* By Magtheridon96
*
* - Tracks unit inventory data.
* - Makes your life a bit easier.
* - This won't win any benchmarks.
*
* Requires:
* ---------
*
* - UnitIndexer by Nestharus
* - hiveworkshop.com/forums/jass-resources-412/system-unit-indexer-172090/
* - RegisterPlayerUnitEvent by Magtheridon96
* - hiveworkshop.com/forums/jass-resources-412/snippet-registerplayerunitevent-203338/
* - Table by Bribe
* - hiveworkshop.com/forums/jass-resources-412/snippet-new-table-188084/
* - OrderEvent by Bribe
* - hiveworkshop.com/forums/jass-resources-412/snippet-order-event-190871/
*
* Optional:
* ---------
*
* - TimerUtils by Vexorian
* - wc3c.net/showthread.php?t=101322
*
* (If you use my version of TimerUtils, this will take advantage of that)
*
* API:
* ----
*
* - struct UnitInventory extends array
*
* - readonly integer size
* - The size of the inventory
* - readonly integer empty
* - The number of empty slots
* - readonly integer full
* - The number of taken slots
*
* - static method operator [] takes unit whichUnit returns thistype
* - Put a unit in between the brackets and you will get the instance
*
* - method getItem takes integer slot returns item
* - Returns the item in a given slot
*
* - method getItemId takes integer slot returns integer
* - Returns the item raw code of an item in a given slot
*
* - method hasItem takes item it returns boolean
* - Determines whether a unit has a certain item or not
*
* - method hasItemId takes integer id returns boolean
* - Determines whether a unit has a certain item type (raw code) or not
*
* - method refresh takes nothing returns nothing
* - Recalculates the size of the inventory. If you have an inventory upgrade, you would need to call this.

This won't win any benchmarks, but it will cache static data and provide you with wrappers to make your lives a bit easier and your codes a bit more readable.
