Struct near_store::TrieUpdate

pub struct TrieUpdate {
    pub trie: Rc<Trie>,
    // some fields omitted
}

Provides a way to access Storage and record changes with future commit.

Fields

trie: Rc<Trie>

Implementations

impl TrieUpdate

pub fn new(trie: Rc<Trie>, root: CryptoHash) -> Self

pub fn trie(&self) -> &Trie

pub fn get(&self, key: &TrieKey) -> Result<Option<Vec<u8>>, StorageError>

pub fn get_ref(
    &self,
    key: &TrieKey
) -> Result<Option<TrieUpdateValuePtr<'_>>, StorageError>

pub fn set(&mut self, trie_key: TrieKey, value: Vec<u8>)

pub fn remove(&mut self, trie_key: TrieKey)

pub fn commit(&mut self, event: StateChangeCause)

pub fn rollback(&mut self)

pub fn finalize(
    self
) -> Result<(TrieChanges, Vec<RawStateChangesWithTrieKey>), StorageError>

pub fn finalize_genesis(self) -> Result<TrieChanges, StorageError>

pub fn iter(
    &self,
    key_prefix: &[u8]
) -> Result<TrieUpdateIterator<'_>, StorageError>

Returns Error if the underlying storage fails

pub fn range(
    &self,
    prefix: &[u8],
    start: &[u8],
    end: &[u8]
) -> Result<TrieUpdateIterator<'_>, StorageError>

pub fn get_root(&self) -> CryptoHash
