Struct ParametricType 

pub struct ParametricType {
    pub constructor: String,
    pub parameters: Vec<TypeParameter>,
}

A parameterized domain type with type parameters.

Examples:

• List<Person> - A list of persons
• Option<City> - An optional city
• Pair<Person, City> - A pair of person and city
• Map<String, Int> - A mapping from strings to integers

Fields

constructor: String

The type constructor name (e.g., “List”, “Option”, “Pair”)

parameters: Vec<TypeParameter>

The type parameters (e.g., ["Person"] for List<Person>)

Implementations

impl ParametricType

pub fn new( constructor: impl Into<String>, parameters: Vec<TypeParameter>, ) -> Self

Creates a new parametric type with the given constructor and parameters.

pub fn list(inner: TypeParameter) -> Self

Creates a List<T> parametric type.

pub fn option(inner: TypeParameter) -> Self

Creates an Option<T> parametric type.

pub fn pair(first: TypeParameter, second: TypeParameter) -> Self

Creates a Pair<A, B> parametric type.

pub fn map(key: TypeParameter, value: TypeParameter) -> Self

Creates a Map<K, V> parametric type.

pub fn validate(&self) -> Result<(), AdapterError>

Validates that the parametric type is well-formed.

Checks:

• Constructor name is not empty
• Number of parameters matches expected arity for known constructors
• All nested parametric types are also well-formed

pub fn arity(&self) -> usize

Returns the arity (number of type parameters) of this parametric type.

pub fn is_monomorphic(&self) -> bool

Checks if this is a monomorphic type (no type parameters).

pub fn contains_parameter(&self, name: &str) -> bool

Checks if this parametric type contains the given type parameter name.

pub fn substitute(&self, from: &str, to: &TypeParameter) -> ParametricType

Substitutes all occurrences of a type parameter with a concrete type.

This is used for type instantiation when applying a parametric type to concrete arguments.

Trait Implementations

impl Clone for ParametricType

fn clone(&self) -> ParametricType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParametricType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ParametricType

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ParametricType

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

Formats the value using the given formatter.

impl Hash for ParametricType

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 ParametricType

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
