Expand description

Enum representing various message types exchanged in the Discovery v4 protocol.

Variants§

§

Ping(Ping)

Represents a ping message sent during liveness checks.

§

Pong(Pong)

Represents a pong message, which is a reply to a PING message.

§

FindNode(FindNode)

Represents a query for nodes in the given bucket.

§

Neighbours(Neighbours)

Represents a neighbour message, providing information about nearby nodes.

§

EnrRequest(EnrRequest)

Represents an ENR request message, a request for Ethereum Node Records (ENR) as per EIP-778.

§

EnrResponse(EnrResponse)

Represents an ENR response message, a response to an ENR request with Ethereum Node Records (ENR) as per EIP-778.

Implementations§

Source§

impl Message

Source

pub const fn msg_type(&self) -> MessageId

Returns the id for this type

Source

pub fn encode(&self, secret_key: &SecretKey) -> (Bytes, B256)

Encodes the UDP datagram, See https://github.com/ethereum/devp2p/blob/master/discv4.md#wire-protocol

The datagram is header || payload where header is hash || signature || packet-type

Source

pub fn decode(packet: &[u8]) -> Result<Packet, DecodePacketError>

Decodes the Message from the given buffer.

Returns the decoded message and the public key of the sender.

Trait Implementations§

Source§

impl Debug for Message

Source§

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Source§

impl PartialEq for Message

Source§

fn eq(&self, other: &Message) -> bool
