Struct EmbeddingDelta 

pub struct EmbeddingDelta {
    pub region: EmbeddingRegion,
    pub changed_ids: Vec<u64>,
    pub vectors: Vec<Vec<f32>>,
    pub generation: u64,
    pub source_peer: String,
    pub created_at_ms: u64,
}

A delta snapshot of changed embeddings in a region.

changed_ids and vectors are parallel slices: changed_ids[i] is the node ID whose new vector is vectors[i].

Fields

region: EmbeddingRegion

The region this delta covers.

changed_ids: Vec<u64>

Node IDs that changed (parallel to vectors).

vectors: Vec<Vec<f32>>

Corresponding new vectors (parallel to changed_ids).

generation: u64

Monotonically increasing version counter.

source_peer: String

Originating peer identifier.

created_at_ms: u64

Wall-clock timestamp (milliseconds since Unix epoch) at creation.

Implementations

impl EmbeddingDelta

pub fn new( region: EmbeddingRegion, generation: u64, source_peer: impl Into<String>, now_ms: u64, ) -> Self

Construct an empty delta for region at generation.

pub fn add_change(&mut self, node_id: u64, vector: Vec<f32>)

Append a single changed node.

pub fn change_count(&self) -> usize

Number of changed nodes recorded in this delta.

pub fn is_empty(&self) -> bool

true when no changes have been recorded.

pub fn estimated_bytes(&self) -> usize

Rough byte estimate for gossip bandwidth accounting.

Formula: 4 * Σ(dim_i) + 8 * n where n is the number of changed nodes and dim_i is the length of the i-th vector.
