Provided Methods§
sourcefn code_size(&self, address: H160) -> U256
fn code_size(&self, address: H160) -> U256
Fetch the code size of an address. Provide a default implementation by fetching the code, but can be customized to use a more performant approach that don’t need to fetch the code.
sourcefn code_hash(&self, address: H160) -> H256
fn code_hash(&self, address: H160) -> H256
Fetch the code hash of an address. Provide a default implementation by fetching the code, but can be customized to use a more performant approach that don’t need to fetch the code.
