impl<'a, SA, T, A> IntoIterator for &'a LinkedListMapper<SA, T, A>
where SA: StorageMapperApi, A: StorageAddress<SA>, T: TopEncode + TopDecode + NestedEncode + NestedDecode + Clone + 'static,

Source§

type Item = LinkedListNode<T>

The type of the elements being iterated over.
Source§

type IntoIter = Iter<'a, SA, T, A>

Which kind of iterator are we turning this into?
Source§

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value. Read more

impl<SA, T> StorageClearable for LinkedListMapper<SA, T>

Source§

fn clear(&mut self)

Clears all the entries owned by the storage.
Source§

impl<SA, T> StorageMapper<SA> for LinkedListMapper<SA, T, CurrentStorage>

Source§

fn new(base_key: StorageKey<SA>) -> Self

Will be called automatically by the #[storage_mapper] annotation generated code.

Source§

fn new_from_address( address: ManagedAddress<SA>, base_key: StorageKey<SA>, ) -> Self

Will be called automatically by the #[storage_mapper_from_address] annotation generated code.
Source§

impl<SA, T> TopEncodeMulti for LinkedListMapper<SA, T>

Source§

fn multi_encode_or_handle_err<O, H>( &self, output: &mut O, h: H, ) -> Result<(), H::HandledErr>

Version of top_encode that can handle errors as soon as they occur. For instance in can exit immediately and make sure that if it returns, it is a success. By not deferring error handling, this can lead to somewhat smaller bytecode.
Source§

fn multi_encode<O>(&self, output: &mut O) -> Result<(), EncodeError>

Attempt to serialize the value to ouput.
Source§

impl<SA, T> TypeAbi for LinkedListMapper<SA, T>

fn type_name() -> TypeName

Source§

fn type_name_rust() -> TypeName

Source§

fn provide_type_descriptions<TDC: TypeDescriptionContainer>( accumulator: &mut TDC, )

A type can provide more than its own name. For instance, a struct can also provide the descriptions of the type of its fields. TypeAbi doesn’t care for the exact accumulator type, which is abstracted by the TypeDescriptionContainer trait.
