Get environmental block hash.

fn balance(&mut self, address: B160) -> Option<(U256, bool)>

Get balance of address and if account is cold loaded.

fn code(&mut self, address: B160) -> Option<(Bytecode, bool)>

Get code of address and if account is cold loaded.

fn code_hash(&mut self, address: B160) -> Option<(B256, bool)>

Get code hash of address and if account is cold loaded.

fn sload(&mut self, address: B160, index: U256) -> Option<(U256, bool)>

Get storage value of address at index and if account is cold loaded.

    target: B160
) -> Option<SelfDestructResult>

Mark an address to be deleted, with funds transferred to target.

fn create(
    &mut self,
    inputs: &mut CreateInputs
) -> (InstructionResult, Option<B160>, Gas, Bytes)
