Struct ItemAttributeModifiers 

pub struct ItemAttributeModifiers { /* private fields */ }

The attribute modifiers of one item stack, as item_attribute_modifier edits them (ItemAttributeModifierEvent’s list). It starts as the stack’s own minecraft:attribute_modifiers, or its item’s, in order.

Implementations

impl ItemAttributeModifiers

pub fn iter(&self) -> Iter<'_, ItemAttributeModifier>

The modifiers, in order.

pub fn len(&self) -> usize

How many modifiers there are.

pub fn is_empty(&self) -> bool

Whether there are none.

pub fn add( &mut self, attribute: Identifier, modifier: AttributeModifier, slot: EquipmentSlotGroup, ) -> bool

addModifier: adds modifier on attribute in the slots of slot, unless attribute already has a modifier with its id. Whether it was added.

pub fn replace( &mut self, attribute: Identifier, modifier: AttributeModifier, slot: EquipmentSlotGroup, )

replaceModifier: puts modifier on attribute in the slots of slot, in place of the one with its id, or at the end.

pub fn remove(&mut self, attribute: &Identifier, id: &Identifier) -> bool

removeModifier: removes the modifier id of attribute. Whether there was one.

pub fn retain( &mut self, keep: impl FnMut(&ItemAttributeModifier) -> bool, ) -> bool

removeIf: keeps only the modifiers keep accepts. Whether any went.

pub fn remove_all_for(&mut self, attribute: &Identifier) -> bool

removeAllModifiersFor: removes every modifier of attribute. Whether any went.

pub fn clear(&mut self)

clearModifiers: removes every modifier.
