Enum PostingUpdate 

pub enum PostingUpdate {
    Append {
        id: u64,
        vector: Vec<f32>,
    },
    Delete {
        id: u64,
    },
}

A single posting update entry containing vector data.

Each entry represents either an append or delete operation on a vector within a centroid’s posting list.

Variants

Append

The type of update: Append or Delete.

Fields

id: u64

Internal vector ID.

vector: Vec<f32>

The full vector data.

Delete

Fields

id: u64

Internal vector ID

Implementations

impl PostingUpdate

pub fn append(id: u64, vector: Vec<f32>) -> Self

Create a new append posting update.

pub fn delete(id: u64) -> Self

Create a new delete posting update.

pub fn is_append(&self) -> bool

Returns true if this is an append operation.

pub fn is_delete(&self) -> bool

Returns true if this is a delete operation.

pub fn id(&self) -> u64

Returns the vector ID.

pub fn vector(&self) -> Option<&[f32]>

Returns the vector data if this is an Append, None if Delete.

pub fn encode(&self, buf: &mut BytesMut)

Encode this posting update to bytes.

Format: type (1 byte) + id (8 bytes LE) + vector (N*4 bytes, each f32 LE)

pub fn decode( buf: &mut impl Buf, dimensions: usize, ) -> Result<Self, EncodingError>

Decode a posting update from bytes.

Requires knowing the dimensions to determine vector size for Append entries.

pub fn encoded_size_append(dimensions: usize) -> usize

Returns the encoded size in bytes for an Append entry with given dimensionality.

pub fn encoded_size_delete() -> usize

Returns the encoded size in bytes for a Delete entry.

pub fn encoded_size(&self) -> usize

Returns the encoded size of this posting update.

Trait Implementations

impl Clone for PostingUpdate

fn clone(&self) -> PostingUpdate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PostingUpdate

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

Formats the value using the given formatter.

impl PartialEq for PostingUpdate

fn eq(&self, other: &PostingUpdate) -> 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.
