Struct ethp2p::Status

pub struct Status {
    pub version: u8,
    pub chain: Chain,
    pub total_difficulty: U256,
    pub blockhash: [u8; 32],
    pub genesis: [u8; 32],
    pub forkid: ForkId,
}

The status message is used in the eth protocol handshake to ensure that peers are on the same network and are following the same fork. The total difficulty and best block hash are used to identify whether or not the requesting client should be sent historical blocks for a full blockchain sync.

When performing a handshake, the total difficulty is not guaranteed to correspond to the block hash. This information should be treated as untrusted.

Fields

version: u8

The current protocol version. For example, peers running eth/66 would have a version of 66.

chain: Chain

The chain id, as introduced in EIP155.

total_difficulty: U256

Total difficulty of the best chain.

blockhash: [u8; 32]

The highest difficulty block hash the peer has seen

genesis: [u8; 32]

The genesis hash of the peer’s chain.

forkid: ForkId

The fork identifier, a CRC32 checksum for identifying the peer’s fork as defined by EIP-2124. This was added in eth/64

Trait Implementations

impl Clone for Status

fn clone(&self) -> Status

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Status

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

Formats the value using the given formatter.

impl Decodable for Status

fn decode(buf: &mut &[u8]) -> Result<Self, DecodeError>

impl Display for Status

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

Formats the value using the given formatter.

impl Encodable for Status

fn length(&self) -> usize

fn encode(&self, out: &mut dyn BufMut)

impl From<Status> for EthMessage

fn from(t: Status) -> Self

Converts to this type from the input type.

impl From<Status> for Request

fn from(t: Status) -> Self

Converts to this type from the input type.

impl From<Status> for Response

fn from(t: Status) -> Self

Converts to this type from the input type.

impl PartialEq<Status> for Status

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

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

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.
