Struct EthApi

pub struct EthApi<Provider, Pool, Network, EvmConfig> {
    pub tx_resp_builder: EthTxBuilder,
    /* 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).

Fields

tx_resp_builder: EthTxBuilder

Transaction RPC response builder.

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.
