Expand description

A raw iterator over the RefTrackingState.

Trait Implementations§

§

type Backend = RefTrackingState

type Error = <TrieBackend<Arc<dyn Storage<<::Header as Header>::Hashing> + 'static>, <::Header as Header>::Hashing, LocalTrieCache<<::Header as Header>::Hashing>> as Backend<<::Header as Header>::Hashing>>::Error

The error type.

source §

fn next_key( &mut self, backend: &Self::Backend ) -> Option<Result<StorageKey, Self::Error>>

Fetches the next key from the storage.

source §

fn next_pair( &mut self, backend: &Self::Backend ) -> Option<Result<(StorageKey, StorageValue), Self::Error>>

Fetches the next key and value from the storage.

source §

fn was_complete(&self) -> bool

Returns whether the end of iteration was reached without an error.
