Required Methods

fn inspect( &self, backend: &mut Backend, env: &mut Env, inspector: &mut dyn InspectorExt, inspect_ctx: Box<dyn Any>, ) -> Result<ExecResultAndState<ExecutionResult>, Report>

fn update_fork_db( &self, ctx: &mut (dyn BackendStrategyContext + 'static), active_fork: Option<&Fork>, mem_db: &CacheDB<EmptyDBWrapper>, backend_inner: &BackendInner, active_journaled_state: &mut JournalInner<JournalEntry>, target_fork: &mut Fork, )

When creating or switching forks, we update the AccountInfo of the contract

fn merge_journaled_state_data( &self, ctx: &mut (dyn BackendStrategyContext + 'static), addr: Address, active_journaled_state: &JournalInner<JournalEntry>, fork_journaled_state: &mut JournalInner<JournalEntry>, )

Clones the account data from the active_journaled_state into the fork_journaled_state

fn merge_db_account_data( &self, ctx: &mut (dyn BackendStrategyContext + 'static), addr: Address, active: &CacheDB<SharedBackend>, fork_db: &mut CacheDB<SharedBackend>, )

fn transact_from_tx( &self, backend: &mut Backend, tx: &TransactionRequest, env: Env, journaled_state: &mut JournalInner<JournalEntry>, inspector: &mut dyn InspectorExt, inspect_ctx: Box<dyn Any>, ) -> Result<(), Report>
