Async vector index trait for remote/shared backends (needs async_trait).
Async vector index trait for remote/shared backends.
The existing VectorIndex is a synchronous,
in-process trait (&mut self, blocking search). That fits compressed
in-memory indexes (TurboQuant) but not remote vector services such as
Qdrant or Elasticsearch, whose clients are async-only and naturally
shared (&self) rather than exclusively borrowed.
AsyncVectorIndex is the async, object-safe counterpart for those
backends. It mirrors the useful subset of VectorIndex — add, remove,
search, filtered search, length, dimensionality — and omits save because
remote backends persist server-side (just as VectorIndex omits load
to stay object-safe). Concrete implementations live in this crate behind
feature flags: the qdrant feature (src/embedding/qdrant.rs) and the
elastic feature (src/embedding/elastic.rs).
The trait has no concrete dependencies beyond async_trait. It is defined
behind the embedding feature so the shared contract stays in the kernel
while the heavy client crates remain opt-in.
