Struct TempoFoundryHandler 

pub struct TempoFoundryHandler<'db, I: FoundryInspectorExt<TempoContext<&'db mut dyn DatabaseExt<TempoEvmFactory>>>> {
    inner: TempoEvmHandler<&'db mut dyn DatabaseExt<TempoEvmFactory>, I>,
    create2_overrides: Vec<(usize, CallInputs)>,
}

Tempo counterpart of EthFoundryHandler. Wraps [TempoEvmHandler] and injects CREATE2 factory redirect logic into the execution loop. Delegates all [Handler] methods to [TempoEvmHandler] for proper Tempo validation, fee collection, AA dispatch, and gas handling.

Will be removed when the next revm release includes bluealloy/revm#3518.

Transfers transaction fees to the block beneficiary’s account.

fn validate_initial_tx_gas( &self, evm: &mut Self::Evm, ) -> Result<InitialAndFloorGas, Self::Error>

Calculates initial gas costs based on transaction type and input data.

fn execution_result( &mut self, evm: &mut Self::Evm, result: <<Self::Evm as EvmTr>::Frame as FrameTr>::FrameResult, result_gas: ResultGas, ) -> Result<ExecutionResult<Self::HaltReason>, Self::Error>

Processes the final execution output.

fn catch_error( &self, evm: &mut Self::Evm, error: Self::Error, ) -> Result<ExecutionResult<Self::HaltReason>, Self::Error>

Handles cleanup when an error occurs during execution.

fn run_system_call( &mut self, evm: &mut Self::Evm, ) -> Result<ExecutionResult<Self::HaltReason>, Self::Error>

Runs the system call.

fn run_without_catch_error( &mut self, evm: &mut Self::Evm, ) -> Result<ExecutionResult<Self::HaltReason>, Self::Error>

Called by [Handler::run] to execute the core handler logic.

fn validate( &self, evm: &mut Self::Evm, ) -> Result<InitialAndFloorGas, Self::Error>

Validates the execution environment and transaction parameters.

fn pre_execution(&self, evm: &mut Self::Evm) -> Result<u64, Self::Error>

Prepares the EVM state for execution.

fn post_execution( &self, evm: &mut Self::Evm, exec_result: &mut FrameResult, init_and_floor_gas: InitialAndFloorGas, eip7702_gas_refund: i64, ) -> Result<ResultGas, Self::Error>

Handles the final steps of transaction execution.

fn load_accounts(&self, evm: &mut Self::Evm) -> Result<(), Self::Error>

Loads access list and beneficiary account, marking them as warm in the [context::Journal].

fn apply_eip7702_auth_list( &self, evm: &mut Self::Evm, ) -> Result<u64, Self::Error>

Processes the authorization list, validating authority signatures, nonces and chain IDs. Applies valid authorizations to accounts.

fn first_frame_input( &mut self, evm: &mut Self::Evm, gas_limit: u64, ) -> Result<FrameInit, Self::Error>

Creates initial frame input using transaction parameters, gas limit and configuration.

fn last_frame_result( &mut self, evm: &mut Self::Evm, frame_result: &mut <<Self::Evm as EvmTr>::Frame as FrameTr>::FrameResult, ) -> Result<(), Self::Error>

Processes the result of the initial call and handles returned gas.

fn run_exec_loop( &mut self, evm: &mut Self::Evm, first_frame_input: <<Self::Evm as EvmTr>::Frame as FrameTr>::FrameInit, ) -> Result<FrameResult, Self::Error>

Executes the main frame processing loop.

fn eip7623_check_gas_floor( &self, _evm: &mut Self::Evm, exec_result: &mut <<Self::Evm as EvmTr>::Frame as FrameTr>::FrameResult, init_and_floor_gas: InitialAndFloorGas, )

Validates that the minimum gas floor requirements are satisfied.

fn refund( &self, evm: &mut Self::Evm, exec_result: &mut <<Self::Evm as EvmTr>::Frame as FrameTr>::FrameResult, eip7702_refund: i64, )

Calculates the final gas refund amount, including any EIP-7702 refunds.

impl<'db, I: FoundryInspectorExt<TempoContext<&'db mut dyn DatabaseExt<TempoEvmFactory>>>> InspectorHandler for TempoFoundryHandler<'db, I>

fn inspect_run( &mut self, evm: &mut Self::Evm, ) -> Result<ExecutionResult<Self::HaltReason>, Self::Error>

Overrides inspect_run to load Tempo fee fields before delegating to the default execution pipeline. This is necessary because the default inspect_run calls validate → validate_against_state_and_deduct_caller directly, bypassing Handler::run where load_fee_fields is normally invoked.

fn inspect_execution( &mut self, evm: &mut Self::Evm, init_and_floor_gas: &InitialAndFloorGas, ) -> Result<FrameResult, Self::Error>

Delegates to [TempoEvmHandler::inspect_execution_with], injecting the CREATE2 factory redirect exec loop. AA multi-call dispatch and gas adjustments are handled by the inner Tempo handler.

type IT = EthInterpreter

The interpreter types used by this handler.

fn inspect_run_exec_loop( &mut self, evm: &mut Self::Evm, first_frame_input: <<Self::Evm as EvmTr>::Frame as FrameTr>::FrameInit, ) -> Result<FrameResult, Self::Error>

Run inspection on execution loop.

fn inspect_run_without_catch_error( &mut self, evm: &mut Self::Evm, ) -> Result<ExecutionResult<Self::HaltReason>, Self::Error>

Run inspection without catching error.

fn inspect_run_system_call( &mut self, evm: &mut Self::Evm, ) -> Result<ExecutionResult<Self::HaltReason>, Self::Error>

Run system call with inspection support.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
