Required Methods

fn actor_open_key_value_entry( &mut self, object_handle: ActorStateHandle, collection_index: CollectionIndex, key: &Vec<u8>, flags: LockFlags ) -> Result<KeyValueEntryHandle, E>

If the key value entry doesn’t exist, it uses the default “Option::None”

fn actor_remove_key_value_entry( &mut self, object_handle: ActorStateHandle, collection_index: CollectionIndex, key: &Vec<u8> ) -> Result<Vec<u8>, E>

Provided Methods

fn actor_remove_key_value_entry_typed<V: ScryptoDecode>( &mut self, object_handle: ActorStateHandle, collection_index: CollectionIndex, key: &Vec<u8> ) -> Result<Option<V>, E>
