Enum Value 

pub enum Value {
    Integer(i64),
    Float(f64),
    Bool(bool),
    Text(ArcString),
    Vector(ArcVec),
    Tensor(Box<Tensor>),
    Spatial(Box<Geometry>),
    TextDoc(Box<Text>),
    Timestamp(Timestamp),
    Null,
}

Unified value type supporting all data modalities

Size optimization: large variants (Text, Tensor, Spatial, TextDoc) are boxed to keep the enum at 16 bytes instead of 40 bytes. This reduces memory amplification for scalar-heavy rows from 8.6x to ~3.5x.

Variants

Integer(i64)

Integer value

Float(f64)

Floating point value

Bool(bool)

Boolean value

Text(ArcString)

Text string (Arc for cheap cloning — just atomic increment)

Vector(ArcVec)

Vector data (for embeddings)

Tensor(Box<Tensor>)

Tensor data (boxed to reduce enum size)

Spatial(Box<Geometry>)

Spatial geometry data (boxed to reduce enum size)

TextDoc(Box<Text>)

Text document for full-text search (boxed to reduce enum size)

Timestamp(Timestamp)

Timestamp data

Null

Null value

Implementations

impl Value

pub fn text(s: String) -> Self

Create a Text value from a String (1 allocation via Arc).

pub fn text_from(s: &str) -> Self

Create a Text value from a &str (1 allocation via Arc).

pub fn tensor(t: Tensor) -> Self

Create a Tensor value

pub fn spatial(g: Geometry) -> Self

Create a Spatial value

pub fn textdoc(t: Text) -> Self

Create a TextDoc value

pub fn to_hash_key(&self) -> String

Convert to a hashable string key for use in HashMap/DashMap lookups. Handles f64 by converting to bits (lossless).

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Value

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Value

impl Hash for Value

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl PartialEq for Value

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

Equality operator ==.

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

impl PartialOrd for Value

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Value

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
