Struct RowSignature 

pub struct RowSignature {
    pub schema_version: u16,
    pub key_id: String,
    pub signed_at: DateTime<Utc>,
    pub bytes: String,
}

Per-row Ed25519 signature persisted alongside the Event fields.

bytes is base64-encoded (URL-safe, no padding) so JSONL rows remain printable / grep-friendly. Verification reconstructs the canonical attestation preimage and checks bytes against the active operator public key (see crate::audit::verify_signed_chain).

Fields

schema_version: u16

Schema version of the attestation preimage encoder used to produce bytes. Mirrors cortex_core::canonical::SCHEMA_VERSION_ATTESTATION. Verifiers MUST fail closed on unknown versions (ADR 0010 §1b).

key_id: String

Public-key fingerprint of the signing operator identity.

signed_at: DateTime<Utc>

Wall-clock timestamp at which the signature was produced. MUST equal the signed_at field that went into the canonical preimage.

bytes: String

Base64 (URL-safe, no padding) of the 64-byte Ed25519 signature. We avoid hex purely to keep the JSONL row narrower; a future schema bump can choose a different encoding.

Trait Implementations

impl Clone for RowSignature

fn clone(&self) -> RowSignature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RowSignature

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RowSignature

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RowSignature

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

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 RowSignature
