Struct VectorAnnotatedRecord 

pub struct VectorAnnotatedRecord {
    pub cid: String,
    pub vector: Vec<f32>,
    pub dimension: usize,
    pub provider_id: String,
    pub ttl_secs: u64,
    pub metadata: HashMap<String, String>,
}

A DHT record that carries an embedded vector alongside the CID it annotates.

VectorAnnotatedRecord is the wire format stored in the DHT; it allows any peer that retrieves the record to immediately compute similarity without fetching additional metadata.

Fields

cid: String

Content identifier this record refers to

vector: Vec<f32>

Embedding vector for the content

dimension: usize

Dimensionality of vector (stored separately for fast validation)

provider_id: String

PeerId (string-encoded) of the peer that published this record

ttl_secs: u64

How long (in seconds) this record should be considered fresh

metadata: HashMap<String, String>

Arbitrary application-level metadata (e.g. content-type, language, …)

Implementations

impl VectorAnnotatedRecord

pub fn new( cid: impl Into<String>, vector: Vec<f32>, provider_id: impl Into<String>, ttl_secs: u64, metadata: HashMap<String, String>, ) -> Self

Construct a new VectorAnnotatedRecord, deriving dimension from vector.

pub fn is_consistent(&self) -> bool

Check whether vector.len() == dimension (should always be true for well-formed records received from trusted peers; useful after deserde).
