Struct Provenance 

pub struct Provenance {
    pub signature: Option<String>,
    pub key_id: Option<String>,
    pub algorithm: Option<String>,
    pub signed_fields: Option<Vec<String>>,
    pub signed_at: Option<DateTime<Utc>>,
}

Provenance information for data integrity verification.

Fields

signature: Option<String>

HMAC-SHA256 signature of the event.

key_id: Option<String>

Key ID used for signing.

algorithm: Option<String>

Signature algorithm (e.g., “hmac-sha256”).

signed_fields: Option<Vec<String>>

Fields included in signature.

signed_at: Option<DateTime<Utc>>

Timestamp when signature was created.

Implementations

impl Provenance

pub fn new(algorithm: impl Into<String>) -> Self

Create new provenance with algorithm.

pub fn with_signature(self, signature: impl Into<String>) -> Self

Set the signature.

pub fn with_key_id(self, key_id: impl Into<String>) -> Self

Set the key ID.

pub fn with_signed_fields(self, fields: Vec<String>) -> Self

Set signed fields.

Trait Implementations

impl Clone for Provenance

fn clone(&self) -> Provenance

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Provenance

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

Formats the value using the given formatter.

impl Default for Provenance

fn default() -> Provenance

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Provenance

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.
