Detailed Description

class sgns::storage::trie::TrieStorage;

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

Public Functions Documentation

function ~TrieStorage

~TrieStorage() override =default

function getPersistentBatch

virtual outcome::result< std::unique_ptr< PersistentTrieBatch > > getPersistentBatch() =0

Reimplemented by: sgns::storage::trie::TrieStorageImpl::getPersistentBatch

function getEphemeralBatch

virtual outcome::result< std::unique_ptr< EphemeralTrieBatch > > getEphemeralBatch() const =0

Reimplemented by: sgns::storage::trie::TrieStorageImpl::getEphemeralBatch

function getPersistentBatchAt

virtual outcome::result< std::unique_ptr< PersistentTrieBatch > > getPersistentBatchAt(
    const base::Hash256 & root
) =0

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

Reimplemented by: sgns::storage::trie::TrieStorageImpl::getPersistentBatchAt

Initializes a batch at the provided state

function getEphemeralBatchAt

virtual outcome::result< std::unique_ptr< EphemeralTrieBatch > > getEphemeralBatchAt(
    const base::Hash256 & root
) const =0

Reimplemented by: sgns::storage::trie::TrieStorageImpl::getEphemeralBatchAt

function getRootHash

virtual base::Buffer getRootHash() const =0

Reimplemented by: sgns::storage::trie::TrieStorageImpl::getRootHash

Root hash of the latest committed trie
