Struct PayloadAttributes 

pub struct PayloadAttributes {
    pub timestamp: u64,
    pub prev_randao: B256,

    pub withdrawals: Option<Vec<Withdrawal>>,
    pub parent_beacon_block_root: Option<B256>,

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for PayloadAttributes

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<Self>

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

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

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 PayloadAttributes

fn clone(&self) -> PayloadAttributes

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PayloadAttributes

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

Formats the value using the given formatter.

impl Decode for PayloadAttributes

Available on crate feature ssz only.

fn is_ssz_fixed_len() -> bool

Returns true if this object has a fixed-length.

fn from_ssz_bytes(bytes: &[u8]) -> Result<Self, DecodeError>

Attempts to decode Self from bytes, returning a DecodeError on failure.

fn ssz_fixed_len() -> usize

The number of bytes this object occupies in the fixed-length portion of the SSZ bytes.

impl Default for PayloadAttributes

fn default() -> PayloadAttributes

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PayloadAttributes

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for PayloadAttributes

Available on crate feature ssz only.

fn is_ssz_fixed_len() -> bool

Returns true if this object has a fixed-length.

fn ssz_append(&self, buf: &mut Vec<u8>)

Append the encoding self to buf.

fn ssz_bytes_len(&self) -> usize

Returns the size (in bytes) when self is serialized.

fn ssz_fixed_len() -> usize

The number of bytes this object occupies in the fixed-length portion of the SSZ bytes.

fn as_ssz_bytes(&self) -> Vec<u8>

Returns the full-form encoding of this object.

impl PartialEq for PayloadAttributes

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for PayloadAttributes

impl StructuralPartialEq for PayloadAttributes

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.
