Struct LiteralValue 

pub struct LiteralValue {
    pub value: ValueKind,
    pub lemma_type: Arc<LemmaType>,
}

Literal value with type. The single value type in semantics.

Fields

value: ValueKind

lemma_type: Arc<LemmaType>

Implementations

impl LiteralValue

pub fn text(s: String) -> Self

pub fn text_with_type(s: String, lemma_type: Arc<LemmaType>) -> Self

pub fn number(n: Ratio<i128>) -> Self

pub fn number_from_decimal(decimal: Decimal) -> Self

pub fn number_with_type(n: Ratio<i128>, lemma_type: Arc<LemmaType>) -> Self

pub fn number_with_type_from_decimal( decimal: Decimal, lemma_type: Arc<LemmaType>, ) -> Self

pub fn quantity_with_type( n: Ratio<i128>, unit: String, lemma_type: Arc<LemmaType>, ) -> Self

Build a Quantity literal carrying a single user-typed unit name. The signature is [(unit_name, 1)]; the normalize pass expands compound names against unit_index so all stored signatures end up in canonical (base-unit) form.

pub fn quantity_with_signature( n: Ratio<i128>, signature: Vec<(String, i32)>, lemma_type: Arc<LemmaType>, ) -> Self

Build a Quantity literal with an explicit signature (already in canonical form). Used by arithmetic when combining operand signatures yields a multi-term result.

pub fn number_interpreted_as_quantity( value: Ratio<i128>, unit_name: String, ) -> Self

Number interpreted as a quantity value in the given unit (e.g. “3 as usd” where 3 is a number). Creates an anonymous one-unit quantity type so computation does not depend on parsing types.

pub fn from_bool(b: bool) -> Self

pub fn from_datetime(dt: &DateTimeValue) -> Self

pub fn magnitude_default_for_decimal_prompt(&self) -> Option<String>

Magnitude string for decimal input prompts (number, single-unit quantity, ratio with percent/permille scaling).

pub fn date(dt: SemanticDateTime) -> Self

pub fn date_with_type(dt: SemanticDateTime, lemma_type: Arc<LemmaType>) -> Self

pub fn time(t: SemanticTime) -> Self

pub fn time_with_type(t: SemanticTime, lemma_type: Arc<LemmaType>) -> Self

pub fn calendar( value: Ratio<i128>, unit: SemanticCalendarUnit, lemma_type: Arc<LemmaType>, ) -> Self

pub fn calendar_from_decimal( value: Decimal, unit: SemanticCalendarUnit, lemma_type: Arc<LemmaType>, ) -> Self

pub fn calendar_with_type( value: Ratio<i128>, unit: SemanticCalendarUnit, lemma_type: Arc<LemmaType>, ) -> Self

pub fn duration_canonical_seconds(&self) -> Ratio<i128>

Derive seconds from a duration quantity’s canonical magnitude.

pub fn calendar_canonical_months(&self) -> Ratio<i128>

Derive months from a calendar quantity’s canonical magnitude.

pub fn ratio(r: Ratio<i128>, unit: Option<String>) -> Self

pub fn ratio_from_decimal(r: Decimal, unit: Option<String>) -> Self

pub fn ratio_with_type( r: Ratio<i128>, unit: Option<String>, lemma_type: Arc<LemmaType>, ) -> Self

pub fn range(left: LiteralValue, right: LiteralValue) -> Self

pub fn display_value(&self) -> String

Get a display string for this value (for UI/output)

pub fn byte_size(&self) -> usize

Approximate byte size for resource limit checks (string representation length)

pub fn get_type(&self) -> &LemmaType

Get the resolved type of this literal

Trait Implementations

impl Clone for LiteralValue

fn clone(&self) -> LiteralValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LiteralValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LiteralValue

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for LiteralValue

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

Formats the value using the given formatter.

impl Eq for LiteralValue

impl Hash for LiteralValue

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 LiteralValue

fn eq(&self, other: &LiteralValue) -> 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 LiteralValue

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

where S: Serializer,

Serialize this value into the given Serde serializer.
