Required Associated Types

type TransactArgs

Type of the transaction argument.

Required Methods

fn new_transact_call( runtime: RuntimeState, gas_limit: U256, data: &[u8], access_list: &[(H160, Vec<H256>)], args: &Self::TransactArgs, ) -> Result<Self, ExitError>

Create a new state from a call transaction.

fn new_transact_create( runtime: RuntimeState, gas_limit: U256, code: &[u8], access_list: &[(H160, Vec<H256>)], args: &Self::TransactArgs, ) -> Result<Self, ExitError>

Create a new state from a create transaction.

fn substate( &mut self, runtime: RuntimeState, gas_limit: U256, is_static: bool, call_has_value: bool, ) -> Result<Self, ExitError>

Create a substate from the current state.

fn merge(&mut self, substate: Self, strategy: MergeStrategy)

Merge a substate to the current state using the given merge strategy.

fn record_codedeposit(&mut self, len: usize) -> Result<(), ExitError>

Record a code deposit.

fn is_static(&self) -> bool

Whether the current state is in the static frame.

fn effective_gas(&self, with_refund: bool) -> U256

Effective gas. The final used gas as reported by the transaction.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
