Struct TempoPayloadAttributes 

pub struct TempoPayloadAttributes {
    inner: EthPayloadAttributes,
    payload_build_budget: Option<Duration>,
    validation_latency_estimate: Option<ValidationLatencyEstimate>,
    timestamp_millis_part: u64,
    extra_data: Bytes,
    proposer_public_key: Option<B256>,
    consensus_context: Option<TempoConsensusContext>,
    subblocks: Arc<dyn Fn() -> Vec<RecoveredSubBlock> + Send + Sync + 'static>,
}

Container type for all components required to build a payload.

It also carries DKG data to be included in the block’s extra_data field.

Fields

inner: EthPayloadAttributes

Inner [EthPayloadAttributes].

payload_build_budget: Option<Duration>

Remaining local proposal budget available to this payload build.

Consensus sets this to the proposal return budget left when it dispatches the build. None means the build was not requested by consensus, so the builder should not stop early for block pacing.

validation_latency_estimate: Option<ValidationLatencyEstimate>

Validation latency estimate for a consensus payload build.

Consensus snapshots this from recent locally validated blocks. None means the builder should use its conservative fallback.

timestamp_millis_part: u64

Milliseconds portion of the timestamp.

extra_data: Bytes

DKG ceremony data to include in the block’s extra_data header field.

This is empty when no DKG data is available (e.g., when the DKG manager hasn’t produced ceremony outcomes yet, or when DKG operations fail).

proposer_public_key: Option<B256>

The proposer’s public key used to resolve the fee recipient from the validator config contract. When None, suggested_fee_recipient from the inner attributes is used as-is.

consensus_context: Option<TempoConsensusContext>

Consensus view for this block

subblocks: Arc<dyn Fn() -> Vec<RecoveredSubBlock> + Send + Sync + 'static>

Subblocks closure.

Implementations

impl TempoPayloadAttributes

pub fn new( proposer_public_key: Option<B256>, timestamp: u64, timestamp_millis_part: u64, extra_data: Bytes, consensus_context: Option<TempoConsensusContext>, subblocks: impl Fn() -> Vec<RecoveredSubBlock> + Send + Sync + 'static, ) -> Self

Creates new TempoPayloadAttributes with inner attributes.

The inner suggested_fee_recipient is always Address::ZERO; the real beneficiary is resolved from the validator config v2 contract by the payload builder.

pub fn extra_data(&self) -> &Bytes

Returns the extra data to be included in the block header.

pub fn proposer_public_key(&self) -> Option<&B256>

Returns the proposer’s public key.

pub fn with_payload_build_budget(self, budget: Duration) -> Self

Sets the remaining local proposal budget for a consensus payload build.

The value should already account for any time spent before the build was requested. The builder treats it as a shared budget for leader build/persist work and validator replay/persist work.

pub fn payload_build_budget(&self) -> Option<Duration>

Returns the consensus-provided build budget, if this is a paced build.

None is intentional for non-consensus builds such as dev or external payload requests; those builds are not constrained by the consensus block-time budget.

pub fn with_validation_latency_estimate( self, estimate: Option<ValidationLatencyEstimate>, ) -> Self

Sets the validation latency estimate for a consensus payload build.

pub fn validation_latency_estimate(&self) -> Option<ValidationLatencyEstimate>

Returns the consensus-provided validation latency estimate.

pub fn timestamp_millis_part(&self) -> u64

Returns the milliseconds portion of the timestamp.

pub fn timestamp_millis(&self) -> u64

Returns the timestamp in milliseconds.

pub fn consensus_context(&self) -> Option<TempoConsensusContext>

Returns the consensus context

pub fn subblocks(&self) -> Vec<RecoveredSubBlock>

Returns the subblocks.

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.
