Required Methods§

Source

fn get_account_state( &self, address: H160, ) -> Result<AccountState, DatabaseError>

Source

fn get_storage_value( &self, address: H160, key: H256, ) -> Result<U256, DatabaseError>

Source

fn get_block_hash(&self, block_number: u64) -> Result<H256, DatabaseError>

Source

fn get_chain_config(&self) -> Result<ChainConfig, DatabaseError>

Source

fn get_account_code(&self, code_hash: H256) -> Result<Code, DatabaseError>

Source

fn get_code_metadata( &self, code_hash: H256, ) -> Result<CodeMetadata, DatabaseError>

Provided Methods§

Source

fn precompile_cache(&self) -> Option<&PrecompileCache>

Access the precompile cache, if available at this database layer.

Source

fn prefetch_accounts(&self, addresses: &[H160]) -> Result<(), DatabaseError>

Prefetch a batch of accounts into the cache. Default: sequential fallback.

Source

fn prefetch_storage(&self, keys: &[(H160, H256)]) -> Result<(), DatabaseError>

Prefetch a batch of storage slots into the cache. Default: sequential fallback.

Dyn Compatibility§

This trait is dyn compatible.

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