Struct LemmaType 

pub struct LemmaType {
    pub name: Option<String>,
    pub specifications: TypeSpecification,
}

A fully resolved type used during evaluation

This combines the type specifications with all overrides already applied.

Fields

name: Option<String>

specifications: TypeSpecification

Implementations

impl LemmaType

pub fn new(name: String, specifications: TypeSpecification) -> Self

Create a new LemmaType with the given name and specifications

pub fn without_name(specifications: TypeSpecification) -> Self

Create a new LemmaType without a name (for standard types and inline fact definitions)

pub fn name(&self) -> &str

Get the name of this type, deriving from specifications if name is None

pub fn is_boolean(&self) -> bool

Check if this type is boolean

pub fn is_scale(&self) -> bool

Check if this type is scale (has units)

pub fn is_number(&self) -> bool

Check if this type is number (dimensionless)

pub fn is_numeric(&self) -> bool

Check if this type is numeric (either scale or number)

pub fn is_text(&self) -> bool

Check if this type is text

pub fn is_date(&self) -> bool

Check if this type is date

pub fn is_time(&self) -> bool

Check if this type is time

pub fn is_duration(&self) -> bool

Check if this type is duration

pub fn is_ratio(&self) -> bool

Check if this type is ratio

pub fn is_veto(&self) -> bool

Check if this type is veto

pub fn has_same_base_type(&self, other: &LemmaType) -> bool

Check if two types have the same standard type specification (ignoring constraints/overrides) This compares only the TypeSpecification variant (Boolean, Number, Scale, Text, etc.) and ignores all constraints like minimum, maximum, decimals, units, options, etc.

pub fn veto_type() -> Self

Create a Veto LemmaType (internal use only - not user-declarable)

pub fn create_default_value(&self) -> Option<LiteralValue>

Create a LiteralValue from this type’s default value, if one exists

pub fn parse_value( &self, raw: &str, span: Span, attribute: &str, doc_name: &str, ) -> Result<LiteralValue, LemmaError>

Parse a raw string value into a LiteralValue according to this type.

Parsing errors are anchored to the provided source location (span, attribute, doc_name).

impl LemmaType

pub fn example_value(&self) -> &'static str

Get an example value string for this type, suitable for UI help text

Trait Implementations

impl Clone for LemmaType

fn clone(&self) -> LemmaType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LemmaType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LemmaType

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for LemmaType

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

Formats the value using the given formatter.

impl Hash for LemmaType

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 LemmaType

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
