Method get_vector

nodedb-vector/src/hnsw/graph/index.rs:216–225

Returns a `&[f32]` view of the stored vector for node `id`. Returns `Some` only when the index dtype is `F32`. For `F16` or `BF16` indexes this method returns `None` — use [`Self::get_vector_bytes`] instead and decode via [`crate::dtype::cast_to_f32`] if an f32 view is needed. In debug builds, calling this on a non-F32 index triggers a `debug_assert!` to flag misuse early. In release builds the
