Struct HttpEventChannel 

pub struct HttpEventChannel {
    pub endpoint: Option<String>,
    pub signal_type: String,
}

HTTP POST channel — Vector http_server source.

Fields

endpoint: Option<String>

Vector ingest endpoint. Defaults to the in-cluster Service http://vector.observability.svc.cluster.local:8080 when unset.

signal_type: String

signal_type tag added to every emitted event. Vector transforms + shinryu’s analytical schema route by this tag (receipt, test-report, ephemeral-marker, …).

Implementations

impl HttpEventChannel

pub fn resolved_endpoint(&self) -> &str

Resolve the endpoint URL, falling back to the in-cluster default.

pub fn signal(signal_type: impl Into<String>) -> Self

Compose an HttpEventChannel pinned to the in-cluster default endpoint (DEFAULT_VECTOR_INGEST, stamped as endpoint: None so Self::resolved_endpoint resolves the same URL on read) and the given signal_type — the ONE substrate primitive owning the 4-token HttpEventChannel { endpoint: None, signal_type: <s>.into() } fixture literal every consumer restated by hand pre-lift.

Pre-lift the same 3-slot chain (endpoint: None, signal_type: <label>.into(), .. for the two-slot struct’s non-existent tail) was hand-authored at TEN workspace-wide sites past the ★★ PRIME-DIRECTIVE ≥ 2 duplication threshold, EVERY one of them the “default-endpoint, name-only” shape (no site in the workspace stamps a non-None endpoint on an HttpEventChannel literal):

• tatara-process::export — five sites: two closed-set ambiguity probes (single_slot_channel, the kind_equals_variant_kind_across_all_carriers probe), plus three round-trip tests (vector_channel_resolves_http_event, export_spec_serde_round_trip, run_marker_labels_round_trip).
• tatara-process::lifetime — two round-trip tests (applicable_exports_filters_by_trigger, exports_round_trip_through_lifetime).
• tatara-process::tagged_union — two closed-set property probes (single_slot_vector_channel_probe, kind_equals_variant_kind_across_all_carriers).
• tatara-reconciler::render — the spec_run_marker_always fixture the ephemeral-export-Job renderer’s tests seed.
• tatara-export-worker::lib — the http_spec fixture the worker’s resolve_run_id tests seed.

Post-lift every callsite reads HttpEventChannel::signal(<label>) and the two-slot struct’s endpoint slot stays owned by the ONE substrate site. The impl Into<String> bound accepts every pre-lift caller shape verbatim — &'static str literals ("receipt", "test-report", "ephemeral-marker"), owned String values (worker fixture’s signal_type.to_string()), and .into()-terminated chains alike — without a per-site coercion.

A future addition (a default-endpoint override for a per-fleet Vector ingress, a signal_type normalization step clamping the tag to shinryu’s allowed set, a per-fleet endpoint seed pulled from a config surface) lands at THIS ONE substrate primitive and every downstream consumer inherits the upgrade mechanically — no per-site edit at any of the ten listed callers or at future test fixtures.

Theory anchor: THEORY.md §VI.1 (generation over composition — the HttpEventChannel { endpoint: None, signal_type: <s>.into() } fixture literal recurred at ten hand-authored sites past the ★★ PRIME-DIRECTIVE ≥ 2 duplication trigger, and is lifted to ONE owner here). THEORY.md §II.1 invariant 5 (composition preserves proofs — a regression that drifted the default- endpoint sentinel from None to a hardcoded string, or reordered the two struct slots, surfaces at the signal_composes_byte_identical_to_pre_lift_literal_across_every_label pin below rather than as silent skew at every downstream fixture).
