Implementations

impl EvmState

pub fn new<P: AsRef<Path>>(path: P) -> Result<Self, Error>

pub fn new_from_genesis(
    evm_state: impl AsRef<Path>,
    evm_genesis: impl AsRef<Path>,
    root_hash: H256,
    timestamp: u64,
    spv_compatibility: bool
) -> Result<Self, Error>

pub fn new_from_parent(
    &self,
    block_start_time: i64,
    spv_compatibility: bool
) -> Self

Ignores all unapplied updates. spv_compatibility - is oneway feature flag, if activated change current version from InitVersion to VersionConsistentHashes (dont change if version is feature).

pub fn load_from<P: AsRef<Path>>(
    path: P,
    evm_persist_feilds: impl Into<EvmPersistState>
) -> Result<Self, Error>

pub fn make_backup(&self) -> Result<PathBuf, Error>

Make backup of current kvs storage.

pub fn save_state(self) -> EvmPersistState

Convert current state into persist one. With persist state and database, one can load evm state back to memory. Consume self, so outer code should call clone(). Cloning KVS is cheap, and most work is in cloning state itself.

pub fn kvs_references(&self) -> usize

pub fn try_commit(
    &mut self,
    slot: u64,
    last_blockhash: [u8; 32]
) -> Result<Option<H256>, Error>

pub fn get_block(&self) -> Option<Block>

Return block header if this state was committed before.

pub fn get_account_state_at(
    &self,
    root: H256,
    address: H160
) -> Option<AccountState>

pub fn get_storage_at(
    &self,
    root: H256,
    address: H160,
    index: H256
) -> Option<H256>
