reth/examples/node-event-hooks/src/main.rs

//! Example for how hook into the node via the CLI extension mechanism without registering
//! additional arguments
//!
//! Run with
//!
//! ```sh
//! cargo run -p node-event-hooks -- node
//! ```
//!
//! This launches a regular reth node and also print:
//! > "All components initialized" – once all components have been initialized
//! > "Node started" – once the node has been started.
