Struct VectorIntrospectionRegistry 

pub struct VectorIntrospectionRegistry { /* private fields */ }

Process-local registry the runtime publishes vector/artifact state into. The shape mirrors storage::queue::presence::ConsumerPresenceRegistry from issue #742: cheap mutex + small hashmap is the right fit because the cardinality is bounded by the operator’s collection count (dozens, not millions) and reads are dominated by snapshot.

Implementations

impl VectorIntrospectionRegistry

pub fn new() -> Self

pub fn publish(&self, vector: VectorMetadata, artifact: ArtifactMetadata)

Publish (or replace) the full introspection row for a collection. Callers in the engine compute the typed shape once at the right moment (collection create, artifact build start / finish, fallback toggle) and hand it over; the registry does not try to derive anything.

pub fn update_artifact(&self, artifact: ArtifactMetadata) -> bool

Replace only the artifact half (build start/finish, fallback toggle, error). No-op if the collection has not been published yet, because the artifact row alone has no useful meaning without the vector row it sits next to.

pub fn forget(&self, collection: &str) -> bool

Drop a collection’s introspection row (e.g. on DROP COLLECTION).

pub fn snapshot(&self) -> Vec<VectorIntrospection>

Snapshot of every tracked collection, deterministically ordered by collection so test assertions and Red UI tables both see a stable shape.

pub fn get(&self, collection: &str) -> Option<VectorIntrospection>

Single-collection lookup, for the per-collection metadata endpoint Red UI hits when it opens one vector’s toolbar.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool
