}

A type that can iterate over consecutive hashed accounts and storage slots, and generate boundary proofs for them, for serving snap/2 (EIP-8189) GetAccountRange/GetStorageRanges requests. Hash-native throughout, unlike StorageRootProvider.

Required Methods

fn account_range( &self, start: B256, limit: B256, response_bytes: usize, ) -> RangeResult<(B256, Account)>

Returns accounts (hash, account) in [start, limit], bounded by response_bytes.

fn storage_root_by_hash(&self, hashed_address: B256) -> ProviderResult<B256>

Returns the storage root for hashed_address without needing its address preimage.

fn storage_range( &self, hashed_address: B256, start: B256, limit: B256, response_bytes: usize, ) -> StorageRangeResult

Same as Self::account_range, but for the storage slots of hashed_address.

Returns None if hashed_address isn’t present in the account trie at the pinned state root, distinct from an account that is present but has no storage.

fn account_range_proof(&self, keys: &[B256]) -> ProviderResult<Vec<Bytes>>

Returns an account-trie boundary proof for the already-hashed keys.

fn storage_range_proof( &self, hashed_address: B256, keys: &[B256], ) -> ProviderResult<Vec<Bytes>>

Same as Self::account_range_proof, but for the storage trie of hashed_address.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
