Required Methods

fn refund( &self, context: &mut Self::Context, exec_result: &mut Self::ExecResult, eip7702_refund: i64, )

Calculate final refund

fn reimburse_caller( &self, context: &mut Self::Context, exec_result: &mut Self::ExecResult, ) -> Result<(), Self::Error>

Reimburse the caller with balance it didn’t spent.

fn reward_beneficiary( &self, context: &mut Self::Context, exec_result: &mut Self::ExecResult, ) -> Result<(), Self::Error>

Reward beneficiary with transaction rewards.

fn output( &self, context: &mut Self::Context, result: Self::ExecResult, ) -> Result<Self::Output, Self::Error>

Main return handle, takes state from journal and transforms internal result to PostExecutionHandler::Output.

fn clear(&self, context: &mut Self::Context)

Clean handler. This handle is called every time regardless of the result of the transaction.

Provided Methods

fn end( &self, _context: &mut Self::Context, end_output: Result<Self::Output, Self::Error>, ) -> Result<Self::Output, Self::Error>

Called when execution ends.

End handle in comparison to output handle will be called every time after execution. While PostExecutionHandler::output will be omitted in case of the error.
