Enum ProvenanceVerification 

pub enum ProvenanceVerification {
    Verified {
        entry: MemoryProvenanceEntry,
        chain_digest: String,
    },
    Unverified {
        reason: UnverifiedReason,
    },
}

Result of looking up provenance for a (store, key) pair.

Verified carries the entry whose chain linkage and hash both check out. Unverified is the fail-closed signal that either no entry was ever written, the chain has been tampered, or the chain cannot currently be read (store unavailable).

Variants

Verified

A chain entry was found and its hash / link verified locally.

Fields

entry: MemoryProvenanceEntry

chain_digest: String

Current aggregate chain digest, useful for correlating receipts with a chain root.

Unverified

No chain entry for this (store, key) pair, OR the chain is currently inaccessible / tampered. reason narrows the case so receipt consumers can log it without swallowing failures.

Fields

reason: UnverifiedReason

Trait Implementations

impl Clone for ProvenanceVerification

fn clone(&self) -> ProvenanceVerification

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProvenanceVerification

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

Formats the value using the given formatter.

impl PartialEq for ProvenanceVerification

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

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 ProvenanceVerification
