Struct Status

pub struct Status {
    pub version: EthVersion,
    pub chain: Chain,
    pub total_difficulty: Uint<256, 4>,
    pub blockhash: FixedBytes<32>,
    pub genesis: FixedBytes<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.

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: EthVersion

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: Uint<256, 4>

Total difficulty of the best chain.

blockhash: FixedBytes<32>

The highest difficulty block hash the peer has seen

genesis: FixedBytes<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

Implementations

impl Status

pub fn builder() -> StatusBuilder

Helper for returning a builder for the status message.

pub fn set_eth_version(&mut self, version: EthVersion)

Sets the EthVersion for the status.

pub fn spec_builder<Spec>(spec: Spec, head: &Head) -> StatusBuilder

where Spec: EthChainSpec + Hardforks,

Create a StatusBuilder from the given [EthChainSpec] and head block.

Sets the chain and genesis, blockhash, and forkid fields based on the [EthChainSpec] and head.

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for Status

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<Status, Error>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<Status, Error>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

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<(), Error>

Formats the value using the given formatter.

impl Decodable for Status

fn decode(b: &mut &[u8]) -> Result<Status, Error>

Decodes the blob into the appropriate type. buf must be advanced past the decoded object.

impl Default for Status

fn default() -> Status

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Status

fn deserialize<__D>( __deserializer: __D, ) -> Result<Status, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Status

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

Formats the value using the given formatter.

impl Encodable for Status

fn length(&self) -> usize

Returns the length of the encoding of this type in bytes.

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

Encodes the type into the out buffer.

impl PartialEq for Status

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for Status

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Status

impl Eq for Status

impl StructuralPartialEq for Status

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
