Struct reth_engine_tree::engine::EngineHandler

source · 
pub struct EngineHandler<T, S, D> { /* private fields */ }
Expand description

A ChainHandler that advances the chain based on incoming requests (CL engine API).

This is a general purpose request handler with network access. This type listens for incoming messages and processes them via the configured request handler.

§Overview

This type is an orchestrator for incoming messages and responsible for delegating requests received from the CL to the handler.

It is responsible for handling the following:

The core logic is part of the EngineRequestHandler, which is responsible for processing the incoming requests.
