}

A trait for iterating over the storage of KeyValueInspect.

Required Methods

fn iter_store( &self, column: Self::Column, prefix: Option<&[u8]>, start: Option<&[u8]>, direction: IterDirection, ) -> BoxedIter<'_, KVItem>

Returns an iterator over the values in the storage.

fn iter_store_keys( &self, column: Self::Column, prefix: Option<&[u8]>, start: Option<&[u8]>, direction: IterDirection, ) -> BoxedIter<'_, KeyItem>

Returns an iterator over keys in the storage.
