Struct EthApi 

pub struct EthApi<N: RpcNodeCore, Rpc: RpcConvert> { /* private fields */ }

Eth API implementation.

This type provides the functionality for handling eth_ related requests. These are implemented two-fold: Core functionality is implemented as EthApiSpec trait. Additionally, the required server implementations (e.g. EthApiServer) are implemented separately in submodules. The rpc handler implementation can then delegate to the main impls. This way EthApi is not limited to [jsonrpsee] and can be used standalone or in other network handlers (for example ipc).

Trait requirements

While this type requires various unrestricted generic components, trait bounds are enforced when additional traits are implemented for this type.

Implementations

impl EthApi<RpcNodeCoreAdapter<NoopProvider, NoopTransactionPool, NoopNetwork, EthEvmConfig>, EthRpcConverter<ChainSpec>>

pub fn builder<Provider, Pool, Network, EvmConfig, ChainSpec>( provider: Provider, pool: Pool, network: Network, evm_config: EvmConfig, ) -> EthApiBuilder<RpcNodeCoreAdapter<Provider, Pool, Network, EvmConfig>, RpcConverter<Ethereum, EvmConfig, EthReceiptConverter<ChainSpec>>>

where RpcNodeCoreAdapter<Provider, Pool, Network, EvmConfig>: RpcNodeCore<Provider: ChainSpecProvider<ChainSpec = ChainSpec>, Evm = EvmConfig>,

Convenience fn to obtain a new EthApiBuilder instance with mandatory components.

Creating an EthApi requires a few mandatory components:

• provider: The type responsible for fetching requested data from disk.
• transaction pool: To interact with the pool, submitting new transactions (e.g. eth_sendRawTransactions).
• network: required to handle requests related to network state (e.g. eth_syncing).
• evm config: Knows how create a new EVM instance to transact,estimate,call,trace.
