Provided Methods

fn estimate_gas_at( &self, request: TransactionRequest, at: BlockId, state_override: Option<StateOverride>, ) -> impl Future<Output = Result<U256, Self::Error>> + Send

Estimate gas needed for execution of the request at the [BlockId].

fn simulate_v1( &self, payload: SimulatePayload, block: Option<BlockId>, ) -> impl Future<Output = SimulatedBlocksResult<Self::NetworkTypes, Self::Error>> + Send

where Self: LoadBlock + FullEthApiTypes,

eth_simulateV1 executes an arbitrary number of transactions on top of the requested state. The transactions are packed into individual blocks. Overrides can be provided.

fn call( &self, request: TransactionRequest, block_number: Option<BlockId>, overrides: EvmOverrides, ) -> impl Future<Output = Result<Bytes, Self::Error>> + Send

Executes the call request (eth_call) and returns the output

fn call_many( &self, bundle: Bundle, state_context: Option<StateContext>, state_override: Option<StateOverride>, ) -> impl Future<Output = Result<Vec<EthCallResponse>, Self::Error>> + Send

where Self: LoadBlock,

Simulate arbitrary number of transactions at an arbitrary blockchain index, with the optionality of state overrides

fn create_access_list_at( &self, request: TransactionRequest, block_number: Option<BlockId>, ) -> impl Future<Output = Result<AccessListResult, Self::Error>> + Send

where Self: Trace,

Creates [AccessListResult] for the [TransactionRequest] at the given [BlockId], or latest block.

fn create_access_list_with( &self, cfg: CfgEnvWithHandlerCfg, block: BlockEnv, at: BlockId, request: TransactionRequest, ) -> Result<AccessListResult, Self::Error>

where Self: Trace,

Creates [AccessListResult] for the [TransactionRequest] at the given [BlockId].

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.
