Methods

impl<'a> EvmTestClient<'a>

pub fn spec_from_json(spec: &ForkSpec) -> Option<Spec>

Converts a json spec definition into spec.

pub fn new(spec: &'a Spec) -> Result<Self, EvmTestError>

Creates new EVM test client with in-memory DB initialized with genesis of given Spec.

pub fn from_pod_state(     spec: &'a Spec,     pod_state: PodState ) -> Result<Self, EvmTestError>

Creates new EVM test client with in-memory DB initialized with given PodState.

pub fn state(&self) -> &State<StateDB>

Return current state.

pub fn call<T: Tracer, V: VMTracer>(     &mut self,     params: ActionParams,     tracer: &mut T,     vm_tracer: &mut V ) -> Result<FinalizationResult, EvmTestError>

Execute the VM given ActionParams and tracer. Returns amount of gas left and the output.

pub fn transact<T: Tracer, V: VMTracer>(     &mut self,     env_info: &EnvInfo,     transaction: SignedTransaction,     tracer: T,     vm_tracer: V ) -> TransactResult<T::Output, V::Output>
