Struct Item 

#[non_exhaustive]
pub struct Item {
    pub id: String,
    pub template: String,
    pub max_stack_size: Option<u8>,
    pub rarity: Option<Rarity>,
    pub components: Vec<(String, Option<Tag>)>,
    pub crafting_remainder: Option<String>,
    pub block: Option<String>,
    pub arm_pose: Option<ArmPose>,
}

An unvalidated draft; Content::declare validates it at load. Refused drafts are reported by the content admission path as native blocks and items of <namespace>: <reason>, without admitting part of that namespace.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

id: String

Identifier in the declaring mod’s namespace.

template: String

The vanilla item it copies, minecraft:<path>.

max_stack_size: Option<u8>

Maximum stack size, validated as 1 to 99 at admission.

rarity: Option<Rarity>

Rarity overriding the template’s.

components: Vec<(String, Option<Tag>)>

An ordered component patch over the template: Some(tag) sets, None removes. Component names are namespaced identifiers, without a removal prefix !.

crafting_remainder: Option<String>

What it leaves in the crafting grid (Item.Properties.craftRemainder): a vanilla item or one of the mod’s own.

block: Option<String>

The block placed by this item, if any.

arm_pose: Option<ArmPose>

The arm pose a humanoid takes holding it, in place of vanilla’s (ArmPose).

Implementations

impl Item

pub fn new(id: impl Into<String>, template: impl Into<String>) -> Item

Start an unvalidated declaration request; content admission checks both identifiers.

Trait Implementations

impl Clone for Item

fn clone(&self) -> Item

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Item

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Item

fn default() -> Item

Returns the “default value” for a type.

impl PartialEq for Item

fn eq(&self, other: &Item) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl StructuralPartialEq for Item

impl Wire for Item

const MIN: usize

Minimum encoded size, used to reject impossible collection lengths.

fn put(&self, out: &mut Writer)

Encodes this value, recording failures on the writer.

fn put_owned(self, out: &mut Writer)

Consumes owned data when a resource’s ownership must cross the boundary.

fn take(input: &mut Reader<'_>) -> Result<Item, WireError>

Decodes one value, leaving any following bytes for the caller.
