}

Dense and sparse vector payloads.

FP16 values are raw IEEE 754 half-precision bits. INT4/INT8/INT16 values are authoritative integer coordinates, not scale-bearing index quantization. Binary values are packed bytes in 32- or 64-bit chunks.

Implementations

impl VectorValue

pub fn encode_fp16(values: &[f32]) -> Result<Self>

Encodes finite f32 coordinates as IEEE 754 half-precision bits.

pub fn data_type(&self) -> DataType

pub fn dimension(&self) -> usize

pub fn is_sparse(&self) -> bool

pub fn to_dense_f32(&self) -> Option<Vec<f32>>

Converts numeric dense forms to f32 for adapters that require it.

FP64 coordinates may be narrowed. The exact collection executor uses Self::to_dense_f64 instead.

pub fn to_dense_f64(&self) -> Option<Vec<f64>>

Decodes all numeric dense forms without narrowing FP64 coordinates.

pub fn to_sparse_f64(&self) -> Option<BTreeMap<u32, f64>>

Trait Implementations

impl Clone for VectorValue

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VectorValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VectorValue

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for VectorValue

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for VectorValue

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
