Struct ethcore::executive::Executive

pub struct Executive<'a, B: 'a + StateBackend> { /* fields omitted */ }

Transaction executor.

Methods

impl<'a, B: 'a + StateBackend> Executive<'a, B>

pub fn new(     state: &'a mut State<B>,     info: &'a EnvInfo,     machine: &'a Machine ) -> Self

Basic constructor.

pub fn from_parent(     state: &'a mut State<B>,     info: &'a EnvInfo,     machine: &'a Machine,     parent_depth: usize,     static_flag: bool ) -> Self

Populates executive from parent properties. Increments executive depth.

pub fn as_externalities<'any, T, V>(     &'any mut self,     origin_info: OriginInfo,     substate: &'any mut Substate,     output: OutputPolicy<'any, 'any>,     tracer: &'any mut T,     vm_tracer: &'any mut V,     static_call: bool ) -> Externalities<'any, T, V, B> where     T: Tracer,     V: VMTracer,

Creates Externalities from Executive.

pub fn transact<T, V>(     &'a mut self,     t: &SignedTransaction,     options: TransactOptions<T, V> ) -> Result<Executed<T::Output, V::Output>, ExecutionError> where     T: Tracer,     V: VMTracer,

This function should be used to execute transaction.

pub fn transact_virtual<T, V>(     &'a mut self,     t: &SignedTransaction,     options: TransactOptions<T, V> ) -> Result<Executed<T::Output, V::Output>, ExecutionError> where     T: Tracer,     V: VMTracer,

Execute a transaction in a "virtual" context. This will ensure the caller has enough balance to execute the desired transaction. Used for extra-block executions for things like consensus contracts and RPCs

pub fn call<T, V>(     &mut self,     params: ActionParams,     substate: &mut Substate,     output: BytesRef,     tracer: &mut T,     vm_tracer: &mut V ) -> Result<FinalizationResult> where     T: Tracer,     V: VMTracer,

Calls contract function with given contract params. NOTE. It does not finalize the transaction (doesn't do refunds, nor suicides). Modifies the substate and the output. Returns either gas_left or vm::Error.

pub fn create<T, V>(     &mut self,     params: ActionParams,     substate: &mut Substate,     output: &mut Option<Bytes>,     tracer: &mut T,     vm_tracer: &mut V ) -> Result<FinalizationResult> where     T: Tracer,     V: VMTracer,

Creates contract with given contract params. NOTE. It does not finalize the transaction (doesn't do refunds, nor suicides). Modifies the substate.
