Enum ReportPayloadShape 

pub enum ReportPayloadShape {
    NdJsonLines,
    OpaqueBytes,
}

How the export worker should embed a TestReportSource’s bytes into the shipped ExportEvent.payload. Lifted as a closed-set typed projection from ReportFormat::payload_shape so the worker’s dispatch is exhaustive on ReportPayloadShape, not on ReportFormat with a silent _ arm. Adding a future ReportFormat variant forces the author to pick its shape here (single edit site); adding a future shape (e.g. compressed) forces every consumer to handle it.

The (shape, JSON-embed-field) pairing — NdJsonLines → "ndjson", OpaqueBytes → "raw_b64" — binds at ONE typed projection (Self::payload_field) rather than at the future worker’s embed-site string literals; pre-lift the field names lived in this enum’s per-variant docstring prose AND would have lived at the worker’s payload.insert("ndjson", …) / payload.insert("raw_b64", …) call sites, where a rename of "raw_b64" → "raw" at one site drifts silently from the docstring and the operator-facing shinryu schema.

Sibling typed-projection lift over a closed enum (rather than matches! / _ arm dispatch): crate::lifetime::TeardownPolicy::should_teardown_on, ExportTrigger::fires_on, crate::phase::ProcessPhase::as_str.

Sibling closed-set Self::ALL lift in lockstep with every other ALL-keyed enum on the same ExportSpec axis (ReportFormat::ALL, ExportTrigger::ALL) and across the crate (crate::phase::ProcessPhase::ALL, crate::signal::ProcessSignal::ALL, crate::boundary::ConditionKind::ALL, crate::lifetime::TeardownPolicy::ALL).

Variants

NdJsonLines

Newline-delimited JSON — split on \n, parse each non-empty line as JSON, embed under payload.<payload_field> (= payload.ndjson) as an array. Field name is the typed projection Self::payload_field so no embed-site literal can drift from this docstring.

OpaqueBytes

Opaque bytes — base64-encode the artifact verbatim, embed under payload.<payload_field> (= payload.raw_b64) as a string. The default shape for anything Vector / shinryu shouldn’t pre-parse. Field name is the typed projection Self::payload_field.

Implementations

impl ReportPayloadShape

pub const ALL: [Self; 2]

The closed set of payload shapes — single source of truth that drives the Self::as_str / fmt::Display pair and the Self::payload_field projection. Adding a third shape (e.g. Compressed → "gzip") lands at one ALL entry + one as_str arm + one payload_field arm + at least one new ReportFormat::payload_shape mapping — exhaustively checked by the compiler (the [Self; 2] array literal forces the arity).

Sibling closed-set lifts on the same ExportSpec axis: ReportFormat::ALL, ExportTrigger::ALL, crate::lifetime::TeardownPolicy::ALL, crate::boundary::ConditionKind::ALL, crate::phase::ProcessPhase::ALL, crate::signal::ProcessSignal::ALL, crate::encapsulates::EncapsulationMode::ALL.

pub const fn as_str(self) -> &'static str

Canonical PascalCase identifier — used by fmt::Display (so format!("{shape}") never reaches for {:?} Debug) and as the operator-facing reason-string projection. No serde wire shape today (the enum is worker-internal), but the identifier matches the sibling-aligned as_str shape that every other closed-set enum in this crate exposes (ReportFormat::as_str, ExportTrigger::as_str, crate::phase::ProcessPhase::as_str). Pinned by report_payload_shape_as_str_unique_per_variant.

pub const fn payload_field(self) -> &'static str

The JSON field name within ExportEvent.payload where the worker embeds this shape’s encoded value — "ndjson" for the newline-split array, "raw_b64" for the base64-encoded opaque string. Pre-lift these names lived ONLY in the per-variant docstring prose; once the export worker lands, a rename at the embed site (payload.insert("ndjson", …) → payload.insert("events", …)) silently drifts from the docstring and from the operator-facing shinryu schema with no compile or runtime signal. Post-lift the worker’s embed site is payload.insert(shape.payload_field().into(), …) and a rename lands at ONE arm here. The per-variant uniqueness invariant (no two shapes alias to the same field name) is pinned by report_payload_shape_payload_field_unique_per_ variant so the worker’s embed site cannot have two shapes collide on the same destination key. Truth table pinned by report_payload_shape_payload_field_truth_table so a future rename lands here at one site, not in the worker.
