Trait Implementations

impl<T> Add<T> for ForkHash

where T: Into<u64>,

type Output = ForkHash

The resulting type after applying the + operator.

fn add(self, block: T) -> ForkHash

Performs the + operation.

impl<T> AddAssign<T> for ForkHash

where T: Into<u64>,

fn add_assign(&mut self, v: T)

Performs the += operation.

impl<'arbitrary> Arbitrary<'arbitrary> for ForkHash

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

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

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

fn clone(&self) -> ForkHash

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ForkHash

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

Formats the value using the given formatter.

impl Decodable for ForkHash

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

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

impl<'de> Deserialize<'de> for ForkHash

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encodable for ForkHash

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<FixedBytes<32>> for ForkHash

fn from(genesis: FixedBytes<32>) -> ForkHash

Converts to this type from the input type.

impl Hash for ForkHash

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 ForkHash

const LEN: usize = 6usize

The maximum length.

impl PartialEq for ForkHash

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

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 ForkHash

impl Eq for ForkHash

impl MaxEncodedLen<alloy_eip2124::::forkid::_#5::{impl#0}::{constant#0}> for ForkHash

impl StructuralPartialEq for ForkHash

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.
