Struct HeadEvent

pub struct HeadEvent {
    pub slot: u64,
    pub block: B256,
    pub state: B256,
    pub epoch_transition: bool,
    pub previous_duty_dependent_root: B256,
    pub current_duty_dependent_root: B256,
    pub execution_optimistic: bool,
}

Event for the Head topic of the beacon API node event stream.

The node has finished processing, resulting in a new head. previous_duty_dependent_root is get_block_root_at_slot(state, compute_start_slot_at_epoch(epoch - 1) - 1) and current_duty_dependent_root is get_block_root_at_slot(state, compute_start_slot_at_epoch(epoch) - 1). Both dependent roots use the genesis block root in the case of underflow.

Fields

slot: u64

The slot number of the event, serialized as a string.

block: B256

The block associated with the event.

state: B256

The state associated with the event.

epoch_transition: bool

A flag indicating if an epoch transition occurred.

previous_duty_dependent_root: B256

The previous duty dependent root.

current_duty_dependent_root: B256

The current duty dependent root.

execution_optimistic: bool

A flag indicating optimistic execution.

Trait Implementations

impl Clone for HeadEvent

fn clone(&self) -> HeadEvent

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HeadEvent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for HeadEvent

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for HeadEvent

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

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 HeadEvent

impl StructuralPartialEq for HeadEvent
