Struct VectorManifest 

pub struct VectorManifest {
    pub space: String,
    pub dim: usize,
    pub shards: u16,
    pub entries: BTreeMap<u16, ContentHash>,
}

A durable vector index’s manifest body.

entries is a BTreeMap so serialization has deterministic key order: a manifest with the same contents always hashes identically, keeping its record revision stable under content-addressed dedup.

Fields

space: String

Caller-declared embedding space, e.g. "bge-small-en-v1.5".

Gonzalo cannot verify a vector came from this model — it never sees the model. This records what the writer declared, which is enough to catch configuration drift when a reader declares something else.

dim: usize

Vector dimension. Every entry in every shard carries exactly this many floats.

shards: u16

Number of shards, fixed when the index is created.

entries: BTreeMap<u16, ContentHash>

Shard id -> the blob holding that shard’s vectors.

Implementations

impl VectorManifest

pub fn new(space: impl Into<String>, dim: usize, shards: u16) -> Self

An empty manifest for a new index.

pub fn key( namespace: impl Into<String>, index_id: impl Into<String>, ) -> RecordKey

The stable RecordKey addressing the index index_id in namespace.

pub fn collection() -> &'static str

The collection segment every vector manifest is addressed under. A KeyPrefix with this collection and no namespace lists every index’s manifest. This is a naming convention for callers, not the set GC unions: GC marks by RecordKind::VectorManifest while scanning every record regardless of collection, and a durable index’s open accepts a manifest key under any namespace.

pub fn to_body(&self) -> Body

Serialize into an inline record Body (deterministic key order).

pub fn from_body(body: &Body) -> Result<Self>

Reconstruct from a record Body. Errors if the bytes are not a valid serialized manifest.
