Struct HelloMessageWithProtocols 

pub struct HelloMessageWithProtocols {
    pub protocol_version: ProtocolVersion,
    pub client_version: String,
    pub protocols: Vec<Protocol>,
    pub port: u16,
    pub id: PeerId,
}

This is a superset of HelloMessage that provides additional protocol Protocol information about the number of messages used by each capability in order to do proper message ID multiplexing.

This type is required for the p2p handshake because the HelloMessage does not share the number of messages used by each capability.

To get the encodable HelloMessage without the additional protocol information, use the HelloMessageWithProtocols::message.

Fields

protocol_version: ProtocolVersion

The version of the p2p protocol.

client_version: String

Specifies the client software identity, as a human-readable string (e.g. “Ethereum(++)/1.0.0”).

protocols: Vec<Protocol>

The list of supported capabilities and their versions.

port: u16

The port that the client is listening on, zero indicates the client is not listening.

By default this is 30303 which is the same as the default discovery port.

id: PeerId

The secp256k1 public key corresponding to the node’s private key.

Implementations

impl HelloMessageWithProtocols

pub const fn builder(id: PeerId) -> HelloMessageBuilder

Starts a new HelloMessageProtocolsBuilder

use reth_eth_wire::HelloMessageWithProtocols;
use reth_network_peers::pk2id;
use secp256k1::SecretKey;
let secret_key = SecretKey::new(&mut rand::rng());
let id = pk2id(&secret_key.public_key());
let status = HelloMessageWithProtocols::builder(id).build();

pub fn message(&self) -> HelloMessage

Returns the raw HelloMessage without the additional protocol information.

pub fn into_message(self) -> HelloMessage

Converts the type into a HelloMessage without the additional protocol information.

pub fn contains_protocol(&self, protocol: &Protocol) -> bool

Returns true if the set of protocols contains the given protocol.

pub fn try_add_protocol(&mut self, protocol: Protocol) -> Result<(), Protocol>

Adds a new protocol to the set.

Returns an error if the protocol already exists.

pub fn with_snap(self, enable: bool) -> Self

Toggles advertisement of the snap/2 satellite protocol (EIP-8189).

snap/2 is negotiated as an RLPx capability and rides alongside eth on the same connection. Disabling removes any advertised snap capability of any version.
