Enum TypeDef

    Regular {

        parent: String,
        overrides: Option<Vec<(String, Vec<String>)>>,

User-defined type as it appears in the source (AST)

Supports these variants:

• Basic type: type money = number
• Basic type extension: type money = number -> decimals 2 -> unit EUR 1.00 -> unit USD 1.18
• From another custom type: type currency from lemma
• Shorthand with overrides: type currency from lemma -> maximum 1000
• Inline type definitions: fact age = [number -> minimum 0 -> maximum 120]

Variants

Regular

Regular named type definition Example: type money = number -> decimals 2

Fields

source_location: Source

name: String

overrides: Option<Vec<(String, Vec<String>)>>

Import

Imported type from another document Example: type currency from lemma or type currency from lemma -> maximum 1000

Fields

source_location: Source

name: String

source_type: String

from: String

overrides: Option<Vec<(String, Vec<String>)>>

Inline

Inline type definition Example: fact age = [number -> minimum 0 -> maximum 120] Example: fact age = [age from lemma] Example: fact age = [age from lemma -> minimum 18]

Fields

source_location: Source

parent: String

overrides: Option<Vec<(String, Vec<String>)>>

fact_ref: FactReference

from: Option<String>

Implementations

impl TypeDef

pub fn source_location(&self) -> &Source

Trait Implementations

impl Clone for TypeDef

fn clone(&self) -> TypeDef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TypeDef

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

Formats the value using the given formatter.

impl PartialEq for TypeDef

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