Struct Attestation 

pub struct Attestation {
    pub attestation_id: AttestationId,
    pub stage_id: StageId,
    pub op_id: Option<OpId>,
    pub intent_id: Option<IntentId>,
    pub kind: AttestationKind,
    pub result: AttestationResult,
    pub produced_by: ProducerDescriptor,
    pub cost: Option<Cost>,
    pub timestamp: u64,
    pub signature: Option<Signature>,
}

The persisted attestation. See module docs for what each field is, what’s in the hash, and what isn’t.

Fields

attestation_id: AttestationId

stage_id: StageId

op_id: Option<OpId>

intent_id: Option<IntentId>

kind: AttestationKind

result: AttestationResult

produced_by: ProducerDescriptor

cost: Option<Cost>

timestamp: u64

Wall-clock seconds since epoch when this attestation was produced. Excluded from attestation_id so the dedup property holds across runs.

signature: Option<Signature>

Implementations

impl Attestation

pub fn new( stage_id: impl Into<StageId>, op_id: Option<OpId>, intent_id: Option<IntentId>, kind: AttestationKind, result: AttestationResult, produced_by: ProducerDescriptor, cost: Option<Cost>, ) -> Self

Build an attestation against a stage, computing its content-addressed id. timestamp defaults to the current wall clock; pass to Attestation::with_timestamp in tests.

pub fn with_timestamp( stage_id: impl Into<StageId>, op_id: Option<OpId>, intent_id: Option<IntentId>, kind: AttestationKind, result: AttestationResult, produced_by: ProducerDescriptor, cost: Option<Cost>, timestamp: u64, ) -> Self

Build an attestation with a caller-controlled timestamp. Used in tests to keep golden hashes stable.

pub fn with_signature(self, signature: Signature) -> Self

Attach a signature. The signature is not part of the hash; the same logical attestation produced by an unsigned harness dedupes against a signed one. Callers who want signature to be part of identity should hash signature into the produced_by.tool string explicitly.

Trait Implementations

impl Clone for Attestation

fn clone(&self) -> Attestation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Attestation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Attestation

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Attestation

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
