Struct Provenance 

pub struct Provenance {
    pub source: EvidenceSource,
    pub state: EvidenceState,
    pub timestamp_basis: TimestampBasis,
    pub user_action_claim: UserActionClaim,
}

The four provenance axes (RFC 0001 D4). They travel together so a Finding can never be constructed without a full provenance record — no silent, misleading default.

Fields

source: EvidenceSource

Where the datum was read from.

state: EvidenceState

Its liveness / derivation state.

timestamp_basis: TimestampBasis

The basis for any timestamp on the finding.

user_action_claim: UserActionClaim

The user-action the evidence supports, as a claim.

Implementations

impl Provenance

pub fn new( source: EvidenceSource, state: EvidenceState, timestamp_basis: TimestampBasis, user_action_claim: UserActionClaim, ) -> Self

Build a full provenance record. All four axes are required.

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<'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.

impl Eq for Provenance

impl PartialEq for Provenance

fn eq(&self, other: &Provenance) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for Provenance

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
