Implementations

impl Inventory

Represents the Inventory of an entity. The inventory has 18 “built-in” slots, with further slots being provided by items equipped in the Loadout sub-struct. Inventory slots are indexed by InvSlotId which is comprised of loadout_idx - the index of the loadout item that provides the slot, 0 being the built-in inventory slots, and slot_idx - the index of the slot within that loadout item.

Currently, it is not supported for inventories to contain items that have items inside them. This is due to both game balance purposes, and the lack of a UI to show such items. Because of this, any action that would result in such an item being put into the inventory (item pickup, unequipping an item that contains items etc) must first ensure items are unloaded from the item. This is handled in inventory\slot.rs

pub fn with_empty() -> Inventory

pub fn with_loadout(loadout: Loadout, body: Body) -> Inventory

pub fn with_loadout_humanoid(loadout: Loadout) -> Inventory

pub fn with_loadout_animal(loadout: Loadout) -> Inventory

pub fn with_recipe_book(self, recipe_book: RecipeBook) -> Inventory

pub fn capacity(&self) -> usize

Total number of slots in in the inventory.

pub fn slots(&self) -> impl Iterator<Item = &Option<Item>>

An iterator of all inventory slots

pub fn overflow_items(&self) -> impl Iterator<Item = &Item>

An iterator of all overflow slots in the inventory

pub fn slots_with_id(&self) -> impl Iterator<Item = (InvSlotId, &Option<Item>)>

An iterator of all inventory slots and their position

pub fn order_by_custom( custom_order: &[CustomOrder], a: &Item, b: &Item, ) -> Ordering

If custom_order is empty, it will always return Ordering::Equal

pub fn sort(&mut self)

Sorts the inventory using the next sort order

pub fn next_sort_order(&self) -> InventorySortOrder

Returns the sort order that will be used when Inventory::sort() is next called

pub fn push(&mut self, item: Item) -> Result<(), (Item, Option<NonZero<u32>>)>

Adds a new item to the fitting slots of the inventory or starts a new group. Returns the item in an error if no space was found.

WARNING: This may make inventory modifications if Err(item) is returned. The second tuple field in the error is the number of items that were successfully inserted into the inventory.

pub fn push_all<I>(&mut self, items: I) -> Result<(), Error>

where I: Iterator<Item = Item>,

Add a series of items to inventory, returning any which do not fit as an error.

pub fn push_all_unique<I>(&mut self, items: I) -> Result<(), Error>

where I: Iterator<Item = Item>,

Add a series of items to an inventory without giving duplicates. (n * m complexity)

Error if inventory cannot contain the items (is full), returning the un-added items. This is a lazy inefficient implementation, as it iterates over the inventory more times than necessary (n^2) and with the proper structure wouldn’t need to iterate at all, but because this should be fairly cold code, clarity has been favored over efficiency.

pub fn insert_at( &mut self, inv_slot_id: InvSlotId, item: Item, ) -> Result<Option<Item>, Item>
