Struct EmbeddingRefBlock 

pub struct EmbeddingRefBlock {
    pub vector_id: Vec<u8>,
    pub source_hash: Vec<u8>,
    pub model: String,
}

EMBEDDING_REF block — vector embedding reference.

Points to a pre-computed vector embedding stored externally (e.g. in a vector database). The source_hash provides a content-addressable link back to the original content that was embedded, using BLAKE3.

Field layout within body:

┌──────────┬───────────┬─────────────┬─────────────────────────┐
│ Field ID │ Wire Type │ Name        │ Description             │
├──────────┼───────────┼─────────────┼─────────────────────────┤
│ 1        │ Bytes     │ vector_id   │ Vector store identifier │
│ 2        │ Bytes     │ source_hash │ BLAKE3 content hash     │
│ 3        │ Bytes     │ model       │ Embedding model name    │
└──────────┴───────────┴─────────────┴─────────────────────────┘

Fields

vector_id: Vec<u8>

Opaque identifier for the vector in the external store.

source_hash: Vec<u8>

BLAKE3 hash of the source content that was embedded.

model: String

Name of the embedding model (e.g. “text-embedding-3-small”).

Implementations

impl EmbeddingRefBlock

pub fn encode_body(&self) -> Vec<u8>

Serialize this block’s fields into a TLV-encoded body.

pub fn decode_body(buf: &[u8]) -> Result<Self, TypeError>

Deserialize an EMBEDDING_REF block from a TLV-encoded body.

Trait Implementations

impl Clone for EmbeddingRefBlock

fn clone(&self) -> EmbeddingRefBlock

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EmbeddingRefBlock

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for EmbeddingRefBlock

fn eq(&self, other: &EmbeddingRefBlock) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
