Struct ItemKey 

pub struct ItemKey(/* private fields */);

An item requested at registration; its load-owned slot identifies the canonical name.

Implementations

impl ItemKey

pub fn id(self, host: &dyn Host) -> String

Side: both. The canonical item id retained by the load-owned registration slot.

impl ItemKey

pub fn data<M>( self, host: &dyn Host, map: &M, ) -> Result<Option<<M as DataMap>::Value>, DataMapError>

where M: DataMap<Entry = ItemKey>,

This item’s value in data map map (Holder.getData), as the server’s data packs and mods’ files left it: the newest file wins, a #tag entry gives every item in the tag its value, replace and remove apply, and conditional files count only when their conditions hold. Ok(None) where the map gives this item no value.

Server side: the server merges the maps when its data loads, on a world’s first open and after every /reload, and a read sees the last load whole, never a mix of two. Readable from data_maps_updated on, in the world and while data reloads. A reload that drops a value drops it here too.
