Struct Attestation 

pub struct Attestation {
    pub key_id: String,
    pub signature: [u8; 64],
    pub signed_at: DateTime<Utc>,
}

Cryptographic proof that an event originated from the named principal.

Wire shape (ADR 0014 §“Signed preimage”). Note: the signature field is the only part of an event payload not included in the canonical preimage (a 64-byte signature cannot sign itself), but key_id and signed_at are included so a captured signature cannot be moved to a different timestamp or rebound to a different key.

Fields

key_id: String

Public-key fingerprint (matches Attestor::key_id).

signature: [u8; 64]

Ed25519 signature over canonical_signing_input.

signed_at: DateTime<Utc>

Wall-clock timestamp the signature was produced at; MUST equal the signed_at field in the preimage that was signed.

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.
