Struct HelloMessageWithProtocols

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

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§
