Enum CanonicalValue 

pub enum CanonicalValue {
    String(CanonicalString),
    Long(i64),
    Double(CanonicalDouble),
    Boolean(bool),
    Date(CanonicalDate),
    DateTime(CanonicalDateTime),
    DateTimeTz(CanonicalDateTimeTz),
    Decimal(DecimalValue),
    Duration(CanonicalDuration),
}

A canonical scalar value with an explicit domain tag.

Variants

String(CanonicalString)

UTF-8 text.

Long(i64)

Signed 64-bit integer; JSON uses a decimal string.

Double(CanonicalDouble)

Finite binary64; JSON uses fixed-width IEEE bits.

Boolean(bool)

Boolean.

Date(CanonicalDate)

Date.

DateTime(CanonicalDateTime)

Timezone-free date-time.

DateTimeTz(CanonicalDateTimeTz)

Timezone-aware date-time.

Decimal(DecimalValue)

Decimal.

Duration(CanonicalDuration)

Duration.

Implementations

impl CanonicalValue

pub const fn value_type(&self) -> ValueTypeTag

Return the closed scalar-domain tag.

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

Compare values within one scalar domain by provider semantics.

This is deliberately separate from representation Ord, which remains the deterministic identity order used by canonical sets and bytes. Compare values only when both belong to the same semantic scalar domain.

Returns None for different domains or a domain without semantic ordering.

Trait Implementations

impl Clone for CanonicalValue

fn clone(&self) -> CanonicalValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CanonicalValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CanonicalValue

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for CanonicalValue

impl From<CanonicalValue> for CompatibilityValueV2

fn from(value: CanonicalValue) -> Self

Converts to this type from the input type.

impl Hash for CanonicalValue

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

Feeds this value into the given Hasher.

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