Execution related functions for the EthApiServer trait in the eth_ namespace.

Provided Methods

fn estimate_gas_at( &self, request: TransactionRequest, at: BlockId, state_override: Option<HashMap<Address, AccountOverride, FbBuildHasher<20>>>, ) -> impl Future<Output = Result<Uint<256, 4>, 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 = Result<Vec<SimulatedBlock<Block<<Self::NetworkTypes as Network>::TransactionResponse, <Self::NetworkTypes as Network>::HeaderResponse>>>, 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<HashMap<Address, AccountOverride, FbBuildHasher<20>>>, ) -> 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.
