Available on crate feature std only.

Some simple messages The version message

Fields

version: u32

The P2P network protocol version

services: ServiceFlags

A bitmask describing the services supported by this node

timestamp: i64

The time at which the version message was sent

receiver: Address

The network address of the peer receiving the message

sender: Address

The network address of the peer sending the message

nonce: u64

A random nonce used to detect loops in the network

user_agent: String

A string describing the peer’s software

start_height: i32

The height of the maximum-work blockchain that the peer is aware of

relay: bool

Whether the receiving peer should relay messages to the sender; used if the sender is bandwidth-limited and would like to support bloom filtering. Defaults to false.

Implementations

impl VersionMessage

pub fn new(
    services: ServiceFlags,
    timestamp: i64,
    receiver: Address,
    sender: Address,
    nonce: u64,
    user_agent: String,
    start_height: i32
) -> VersionMessage

Constructs a new version message with relay set to false

Trait Implementations

impl Clone for VersionMessage

fn clone(&self) -> VersionMessage

Returns a copy of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VersionMessage

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

Formats the value using the given formatter.

impl Decodable for VersionMessage

fn consensus_decode_from_finite_reader<R: Read + ?Sized>(
    r: &mut R
) -> Result<VersionMessage, Error>

Decode Self from a size-limited reader.

fn consensus_decode<R: Read + ?Sized>(
    r: &mut R
) -> Result<VersionMessage, Error>

Decode an object with a well-defined format.

impl Encodable for VersionMessage

fn consensus_encode<R: Write + ?Sized>(&self, r: &mut R) -> Result<usize, Error>

Encode an object with a well-defined format. Returns the number of bytes written on success.

impl PartialEq<VersionMessage> for VersionMessage

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

This method tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
