Get block hash by number.

fn canonical_hashes_range( &self, start: u64, end: u64, ) -> Result<Vec<FixedBytes<32>>, ProviderError>

Get headers in range of block hashes or numbers

fn convert_block_hash( &self, hash_or_number: HashOrNumber, ) -> Result<Option<FixedBytes<32>>, ProviderError>

impl<Provider> HashedPostStateProvider for LatestStateProviderRef<'_, Provider>

where Provider: DBProvider,

fn hashed_post_state( &self, bundle_state: &BundleState, ) -> Result<HashedPostState, ProviderError>

Returns the HashedPostState of the provided BundleState, materializing zero-valued updates for parent storage of accounts that were destroyed but remain in the post-state.

impl<Provider> StateProofProvider for LatestStateProviderRef<'_, Provider>

where Provider: DBProvider + StorageSettingsCache,

fn proof( &self, input: TrieInput, address: Address, slots: &[FixedBytes<32>], ) -> Result<AccountProof, ProviderError>

Get account and storage proofs of target keys in the HashedPostState on top of the current state.

fn multiproof( &self, input: TrieInput, targets: MultiProofTargets, ) -> Result<MultiProof, ProviderError>

fn multiproof_v2( &self, targets: MultiProofTargetsV2, _requires_masks: bool, ) -> Result<DecodedMultiProofV2, ProviderError>

Generate a V2 decoded multiproof for target hashed accounts and storage slots against the provider’s state.

fn witness( &self, input: TrieInput, target: HashedPostState, mode: ExecutionWitnessMode, ) -> Result<Vec<Bytes>, ProviderError>

Get trie witness for provided state using the given witness generation mode.

impl<Provider> StateProvider for LatestStateProviderRef<'_, Provider>

where Provider: DBProvider + BlockHashReader + StorageSettingsCache,

fn storage( &self, account: Address, storage_key: FixedBytes<32>, ) -> Result<Option<Uint<256, 4>>, ProviderError>

Get storage by plain (unhashed) storage key slot.

fn account_code( &self, addr: &Address, ) -> Result<Option<Bytecode>, ProviderError>

Get account code by its address.

fn account_balance( &self, addr: &Address, ) -> Result<Option<Uint<256, 4>>, ProviderError>

Get account balance by its address.

fn account_nonce(&self, addr: &Address) -> Result<Option<u64>, ProviderError>

Get account nonce by its address.

fn into_evm_state_provider(self) -> EvmStateProviderAdapter<Self>

fn state_root_from_nodes( &self, input: TrieInput, ) -> Result<FixedBytes<32>, ProviderError>

Returns the state root of the HashedPostState on top of the current state but reuses the intermediate nodes to speed up the computation. It’s up to the caller to construct the prefix sets and inform the provider of the trie paths that have changes.

fn state_root_with_updates( &self, hashed_state: HashedPostState, ) -> Result<(FixedBytes<32>, TrieUpdates), ProviderError>

Returns the state root of the HashedPostState on top of the current state with trie updates to be committed to the database.

fn state_root_from_nodes_with_updates( &self, input: TrieInput, ) -> Result<(FixedBytes<32>, TrieUpdates), ProviderError>

Returns state root and trie updates. See StateRootProvider::state_root_from_nodes for more info.
