Struct BlockKey 

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

A block requested once through Registrar::block_key. Its load-owned slot survives reload.

Implementations

impl BlockKey

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

Side: both. The canonical block id retained by the load-owned registration slot. An invalid slot is a boundary error, including when a wasm guest supplies it.

impl BlockKey

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

where M: DataMap<Entry = BlockKey>,

This block’s value in data map map (Holder.getData), as for ItemKey::data: the server’s merged value after every pack and mod file, Ok(None) where it has none.
