Struct ArtifactSource 

pub struct ArtifactSource {
    pub receipts: Option<ReceiptsSource>,
    pub test_report: Option<TestReportSource>,
    pub process_snapshot: Option<ProcessSnapshotSource>,
    pub run_marker: Option<RunMarkerSource>,
}

What artifact this export ships out.

Exactly-one-Option pattern, matching the rest of the typescape (Intent, Lifetime). Adding a new artifact kind is additive on the wire — existing JSON keeps deserializing unchanged.

Fields

receipts: Option<ReceiptsSource>

Every ReceiptEnvelope emitted by this Process during its lifetime — the BLAKE3-chained typed attestation stream.

test_report: Option<TestReportSource>

A test report stored in a ConfigMap by an in-cluster test runner (Job, test harness, closed-loop probe). Worker reads the ConfigMap, packages it per format, and forwards.

process_snapshot: Option<ProcessSnapshotSource>

The Process’s own ProcessSpec + ProcessStatus snapshot at teardown time, as canonical JSON. Useful for post-mortems on failed ephemeral runs.

run_marker: Option<RunMarkerSource>

A small synthetic event — start/end of run markers, cohort tags, experiment correlation. Worker emits a single timestamped event with the declared labels.

Implementations

impl ArtifactSource

pub fn variant(&self) -> Result<ArtifactVariant<'_>, ArtifactError>

Resolve to exactly one variant. Errors on zero or many.

One-line inherent forwarder that delegates the sweep body to the substrate primitive crate::tagged_union::TaggedUnion::variant — every production .variant() site on ProcessSpec dispatches through this ONE default body so the resolve-sweep pattern lives at ONE substrate site. The inherent surface stays load-bearing so consumer callsites don’t need use TaggedUnion.

Trait Implementations

impl Clone for ArtifactSource

fn clone(&self) -> ArtifactSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArtifactSource

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

Formats the value using the given formatter.

impl Default for ArtifactSource

fn default() -> ArtifactSource

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ArtifactSource

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for ArtifactSource

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl Serialize for ArtifactSource

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TaggedUnion for ArtifactSource

const KIND_LIST: &'static str = ARTIFACT_KIND_LIST

Slash-joined operator diagnostic literal — the payload of TaggedUnionError::empty when no slot is populated on this tagged union. Pinned against <Self::Kind as tatara_closed_set::ClosedSet>::labels_joined("/") by assert_kind_list_matches_closed_set so a variant added to Self::Kind without updating this constant (or a renamed variant) fails-loudly at the testkit boundary.

type Kind = ArtifactKind

The closed-set discriminator over this tagged-union’s variants. Bound to tatara_closed_set::ClosedSet so the generic diagnostic-stability testkit (assert_kind_list_matches_closed_set) can project <Self::Kind as ClosedSet>::labels_joined("/") against Self::KIND_LIST byte-identically. Additionally bound to VariantSelector<Self> so Self::variant’s default body can dispatch k.select(self) at each [ClosedSet::ALL] entry generically.

type Error = ArtifactError

The typed error carrier returned by the parent’s inherent .variant() method — projects onto the shared TaggedUnionError contract so resolve_or_err’s two-arm dispatch reaches every implementor uniformly.

fn variant( &self, ) -> Result<<Self::Kind as VariantSelector<Self>>::Variant<'_>, Self::Error>

Sweep over every Self::Kind discriminator in ClosedSet::ALL order, projecting each into the parent’s borrowed variant view via VariantSelector::select, and resolve to exactly one populated variant through resolve_or_err. Errors on zero (with Self::KIND_LIST carried on the TaggedUnionError::empty arm) or many.

impl VariantSelector<ArtifactSource> for ArtifactKind

type Variant<'a> = ArtifactVariant<'a>

The borrowed-view enum returned by the parent’s inherent .variant() method — one arm per closed-set variant, each arm carrying a &'a reference into the parent’s populated slot. Bound generically here so TaggedUnion::variant’s default body can name the return type without restating it per parent. Additionally bound to VariantKind<Self> so the reverse projection Variant<'a> → Self is closed at the trait boundary — every implementor’s borrowed view knows its addressing Kind through ONE typed contract, and the substrate testkit assert_variant_round_trip composes select (forward) with variant_kind (reverse) generically.

fn select<'a>(self, parent: &'a ArtifactSource) -> Option<ArtifactVariant<'a>>

where Self: 'a,

Project a &'a P borrow into the optional typed variant view for self (the addressed discriminator). Returns None iff the matching slot on P is None. Composes the closed-set sweep TaggedUnion::variant loops over.
