Required Methods

fn get<'a>( &self, key: impl Borrow<K::SelfType<'a>> ) -> Result<MultimapValue<'_, V>, StorageError>where K: 'a,

Returns an iterator over all values for the given key. Values are in ascending order.

fn range<'a, KR>( &self, range: impl RangeBounds<KR> + 'a ) -> Result<MultimapRange<'_, K, V>, StorageError>where K: 'a, KR: Borrow<K::SelfType<'a>> + 'a,

fn len(&self) -> Result<u64, StorageError>

fn is_empty(&self) -> Result<bool, StorageError>

Provided Methods

fn iter(&self) -> Result<MultimapRange<'_, K, V>, StorageError>

Returns an double-ended iterator over all elements in the table. Values are in ascending order.
