Class StoragePreconditions

java.lang.Object
net.fabricmc.fabric.api.transfer.v1.storage.StoragePreconditions
@Experimental @Deprecated public class StoragePreconditions extends Object
Deprecated.
Experimental feature, we reserve the right to remove or change it without further notice. The transfer API is a complex addition, and we want to be able to correct possible design mistakes.
Preconditions that can be used when working with storages.

In particular, notNegative(long) or notBlankNotNegative(net.fabricmc.fabric.api.transfer.v1.storage.TransferVariant<?>, long) can be used by implementations of Storage.insert(T, long, net.fabricmc.fabric.api.transfer.v1.transaction.TransactionContext) and Storage.extract(T, long, net.fabricmc.fabric.api.transfer.v1.transaction.TransactionContext) to fail-fast if the arguments are invalid.
