fn transient_set_storage(&mut self, key: Vec<u8>, value: U256) -> Result<()>

Stores a value for given key.

fn exists(&self, address: &Address) -> Result<bool>

Determine whether an account exists.

fn exists_and_not_null(&self, address: &Address) -> Result<bool>

Determine whether an account exists and is not null (zero balance/nonce, no code).

fn origin_balance(&self) -> Result<U256>

Balance of the origin account.

fn balance(&self, address: &Address) -> Result<U256>

Returns address balance.

fn blockhash(&mut self, number: &U256) -> Result<H256>

Returns the hash of one of the 256 most recent complete blocks.

fn create( &mut self, gas: &U256, value: &U256, code: &[u8], address_scheme: CreateContractAddress ) -> Result<Result<ContractCreateResult, TrapKind>>

Creates new contract.

fn call( &mut self, gas: &U256, sender_address: &Address, receive_address: &Address, value: Option<U256>, data: &[u8], code_address: &Address, call_type: CallType ) -> Result<Result<MessageCallResult, TrapKind>>

Message call.

fn extcode(&self, address: &Address) -> Result<Option<Arc<Bytes>>>

Returns code at given address
