Enum ValueKind 

pub enum ValueKind {
    Number(RationalInteger),
    Measure(RationalInteger, Vec<(String, i32)>),
    Text(String),
    Date(SemanticDateTime),
    Time(SemanticTime),
    Boolean(bool),
    Ratio(RationalInteger, Option<String>),
    Range(Box<LiteralValue>, Box<LiteralValue>),
}

Value payload (shape of a literal). No type attached. Measure unit is required; Ratio unit is optional (see plan ratio-units-optional.md).

Variants

Number(RationalInteger)

Measure(RationalInteger, Vec<(String, i32)>)

Measure: magnitude in canonical (base-unit) space + unit signature.

At bind time the user-facing value is multiplied by unit.factor to produce the stored magnitude; materialization divides back. The signature carries the declared unit name(s) and is always in canonical form (sorted, no zero exponents).

Text(String)

Date(SemanticDateTime)

Time(SemanticTime)

Boolean(bool)

Ratio(RationalInteger, Option<String>)

Ratio: value + optional unit

Range(Box<LiteralValue>, Box<LiteralValue>)

Implementations

impl ValueKind

pub fn as_decimal_magnitude(&self) -> Result<Decimal, String>

Decimal magnitude for numeric variants (number, measure, ratio).

Trait Implementations

impl Clone for ValueKind

fn clone(&self) -> ValueKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValueKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ValueKind

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for ValueKind

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

Formats the value using the given formatter.

impl Eq for ValueKind

impl Hash for ValueKind

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,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ValueKind

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

impl Serialize for ValueKind

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
