pub fn set_block_number(&mut self, number: u64)

Set the current block number.

pub fn env_info(author: Address) -> EnvInfo

Create a static info structure of the environment.

pub fn deploy<C>(     &self,     constructor: C,     call: Call ) -> Result<Call<Address>, Error> where     C: ContractFunction<Output = Address> + Constructor,

Deploy the contract with the given code.

pub fn deploy_code(     &self,     code: Vec<u8>,     call: Call,     entry_source: Option<Arc<Source>>,     linker: &Linker ) -> Result<Call<Address>, Error>

Deploy the contract with the given code.

pub fn call_default(     &self,     address: Address,     call: Call ) -> Result<Call<()>, Error>

Perform a call against the given address' fallback function.

This is the same as a straight up transfer.

pub fn logs<'a, P>(&'a self, log: P) -> LogDrainer<'a, P> where     P: ParseLog + LogFilter,

Setup a log drainer that drains the specified logs.

pub fn raw_logs(&self) -> Result<Ref<HashMap<Hash, Vec<LogEntry>>>, Error>

Access raw underlying logs.

Note: it is important that the Ref is released as soon as possible since this would otherwise cause borrowing issues for other operations.

pub fn has_logs(&self) -> Result<bool, Error>

Check if we still have unclaimed logs.

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

Query the balance of the given account.

pub fn add_balance<W: Into<U256>>(     &self,     address: Address,     wei: W ) -> Result<(), Error>

Add the given number of wei to the provided account.
