+/**
+  * Change the location of an item within the game's inventory system.<br>
+  * <br>
+  * The data portion of this packet defines a player, an item, and a destination.
+  * After the packet is received by the client, the item will be guaranteed to be within the player's inventory in the codified location.
+  * The "inventory" in this case includes both the player's literal grid inventory and their available equipment slots.
+  * Where the item was before it was moved is not specified.<br>
+  * <br>
+  * This packet is a complementary packet that simulates a lazy TCP-like approach to coordinating item manipulation.
+  * In some cases, the client will (appear to) proceed with what it intended to do without waiting for the server to confirm.
+  * For example, grabbing an item from an inventory position will generate a `MoveItemMessage` that defines "the player's cursor" as a destination.
+  * The client will "attach to the player's cursor" without waiting for an `ObjectAttachMessage` from the server which echoes the destination.
+  * The change is observable.
+  * Inversely, the client is blocked from detaching the item from "the player's cursor" and putting it back into the inventory on its own.
+  * It waits until it receives an `ObjectAttachMessage` in confirmation.<br>
+  * <br>
+  *  Destination codes:<br>
+  * `0x80` - pistol slot 1<br>
+  * `0x81` - pistol slot 2<br>
+  * `0x82` - rifle slot 1<br>
+  * `0x83` - rifle slot 2<br>
+  * `0x84` - melee/knife slot<br>
+  * `0x85` - mystery slot<br>
+  * `0x86` - grid inventory (1,1)<br>
+  * `0x00FA` is a special dest/extra code that "attaches the item to the player's cursor"
+  * @param player_guid the player
+  * @param item_guid the item
+  * @param slot a codified location within an inventory, and overlapping the player's holsters if need be;
+  *             8u (0 - 127 or `0x80 - 0xFF`) or
+  *             16u (128 - 32767 or `0x0080 - 0x7FFF`)
+  * @see `MoveItemMessage`, `objectcreate\ObjectClass.SLOT_BLOCKER`
