virtual outcome::result< std::unique_ptr< EphemeralTrieBatch > >	getEphemeralBatchAt (const RootHash &root) const =0

Detailed Description

Grants access to the storage in two ways:

• persistent batch that will written back to the storage after commit() call
• ephemeral batch, all changes to which are left in memory and thus the main storage is never changed by it

Member Function Documentation

virtual outcome::result<std::unique_ptr<EphemeralTrieBatch> > kagome::storage::trie::TrieStorage::getEphemeralBatchAt ( const RootHash &  root ) const

pure virtual

Implemented in kagome::storage::trie::TrieStorageImpl.

virtual outcome::result<std::unique_ptr<PersistentTrieBatch> > kagome::storage::trie::TrieStorage::getPersistentBatchAt ( const RootHash &  root )

pure virtual

Initializes a batch at the provided state

Warning

if the batch is committed, the trie will still switch to its state, creating a 'fork'

Implemented in kagome::storage::trie::TrieStorageImpl.
