Struct ForkId

pub struct ForkId {
    pub hash: ForkHash,
    pub next: u64,
}

A fork identifier as defined by EIP-2124. Serves as the chain compatibility identifier.

Fields

hash: ForkHash

CRC32 checksum of the all fork blocks and timestamps from genesis.

next: u64

Next upcoming fork block number or timestamp, 0 if not yet known.

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for ForkId

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

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

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

fn clone(&self) -> ForkId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ForkId

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

Formats the value using the given formatter.

impl Decodable for ForkId

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

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

impl<'de> Deserialize<'de> for ForkId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encodable for ForkId

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 From<EnrForkIdEntry> for ForkId

fn from(entry: EnrForkIdEntry) -> ForkId

Converts to this type from the input type.

impl From<ForkId> for EnrForkIdEntry

fn from(fork_id: ForkId) -> EnrForkIdEntry

Converts to this type from the input type.

impl Hash for ForkId

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl MaxEncodedLenAssoc for ForkId

const LEN: usize = 16usize

The maximum length.

impl PartialEq for ForkId

fn eq(&self, other: &ForkId) -> 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 ForkId

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 ForkId

impl Eq for ForkId

impl MaxEncodedLen<alloy_eip2124::::forkid::_#13::{impl#0}::{constant#0}> for ForkId

impl StructuralPartialEq for ForkId

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.
