}

K2K partial centroid update from a worker.

In distributed KMeans, each worker computes partial sums for centroids from its data partition.

Fields

id: MessageId

Message ID.

worker_id: u64

Worker ID.

iteration: u64

Iteration number.

cluster_id: u32

Cluster ID this update is for.

point_count: u32

Number of points assigned to this cluster on this worker.

coord_sum_fp: [i64; 8]

Partial sum of coordinates (fixed-point, up to 8 dimensions).

n_dims: u8

Number of dimensions.

Trait Implementations

impl Archive for K2KPartialCentroid

where MessageId: Archive, u64: Archive, u32: Archive, [i64; 8]: Archive, u8: Archive,

type Archived = ArchivedK2KPartialCentroid

unsafe fn resolve( &self, pos: usize, resolver: Self::Resolver, out: *mut Self::Archived, )

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for K2KPartialCentroid

fn clone(&self) -> K2KPartialCentroid

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for K2KPartialCentroid

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

Formats the value using the given formatter.
