Struct snarkos_network::context::handshakes::Handshakes

pub struct Handshakes { /* fields omitted */ }

Stores the address and latest state of peers we are handshaking with.

Implementations

impl Handshakes

pub fn new() -> Self

Construct a new store of connected peer Handshakes.

pub async fn send_request<'_>(
    &'_ mut self,
    version: u64,
    height: u32,
    address_sender: SocketAddr,
    address_receiver: SocketAddr
) -> Result<(), HandshakeError>

Create a new handshake with a peer and send a handshake request to them. If the request is sent successfully, the handshake is stored and returned.

pub async fn receive_any<'_>(
    &'_ mut self,
    version: u64,
    height: u32,
    local_address: SocketAddr,
    peer_address: SocketAddr,
    reader: TcpStream
) -> Result<(Handshake, SocketAddr), HandshakeError>

Receive the first message upon accepting a peer connection. If the message is a Version: 1. Create a new handshake. 2. Send a handshake response. 3. If the response is sent successfully, store the handshake. 4. Return the handshake and your address as seen by sender. If the message is a Verack: 1. Get the existing handshake. 2. Mark the handshake as accepted. 3. Send a request for peers. 4. Return the accepted handshake and your address as seen by sender.

pub async fn receive_request<'_>(
    &'_ mut self,
    message: Version,
    address_receiver: SocketAddr
) -> Result<(), HandshakeError>

Receive a handshake request from a connected peer. Update the handshake channel address if needed. Send a handshake response.

pub async fn accept_response<'_>(
    &'_ mut self,
    address: SocketAddr,
    message: Verack
) -> Result<(), HandshakeError>

Accept a handshake response from a connected peer.

pub fn get_state(&self, address: SocketAddr) -> Option<HandshakeState>

Returns the state of the handshake at a peer address.
