Enum Value 

pub enum Value {
    String(String),
    Number(Decimal),
    Integer(i64),
    Date(NaiveDate),
    Boolean(bool),
    Amount(Amount),
    Position(Box<Position>),
    Inventory(Box<Inventory>),
    StringSet(Vec<String>),
    Metadata(Box<Metadata>),
    Interval(Interval),
    Object(Box<BTreeMap<String, Self>>),
    Null,
}

A value that can result from evaluating a BQL expression.

Heavy variants (Inventory, Position, Metadata, Object) are boxed to reduce the size of the enum from 120 bytes to 32 bytes, improving cache efficiency when processing large result sets.

Variants

String(String)

String value.

Number(Decimal)

Numeric value.

Integer(i64)

Integer value.

Date(NaiveDate)

Date value.

Boolean(bool)

Boolean value.

Amount(Amount)

Amount (number + currency).

Position(Box<Position>)

Position (amount + optional cost). Boxed to reduce enum size.

Inventory(Box<Inventory>)

Inventory (aggregated positions). Boxed to reduce enum size.

StringSet(Vec<String>)

Set of strings (tags, links).

Metadata(Box<Metadata>)

Metadata dictionary. Boxed to reduce enum size.

Interval(Interval)

Interval for date arithmetic.

Object(Box<BTreeMap<String, Self>>)

Structured object (for entry, meta columns). Boxed to reduce enum size.

Null

NULL value.

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 PartialEq for Value

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