Struct ItemEnchantments 

pub struct ItemEnchantments {
    pub levels: FxHashMap<Identifier, u32>,
}

Enchantments stored on an item. Maps enchantment key to level.

Used by both the minecraft:enchantments component (on enchanted items) and the minecraft:stored_enchantments component (on enchanted books).

Vanilla moved tooltip visibility to the separate TOOLTIP_DISPLAY component.

Fields

levels: FxHashMap<Identifier, u32>

Implementations
