Enum Type 

pub enum Type {
    Primitive(PrimitiveType),
    Named {
        name: String,
        args: Vec<Type>,
    },
    Function {
        params: Vec<Type>,
        ret: Box<Type>,
    },
    Var(TypeVarId),
    Array(Box<Type>),
    Tuple(Vec<Type>),
}

A type in Husk’s core type language.

Variants

Primitive(PrimitiveType)

A primitive type such as i32, bool, String, or ().

Named

A named, possibly generic type such as Option<T> or Result<T, E>.

Fields

name: String

The name of the type constructor (e.g., “Option”, “Result”, “MyType”).

args: Vec<Type>

Type arguments applied to the constructor.

Function

A function type: (T1, T2, ...) -> R.

Fields

params: Vec<Type>

ret: Box<Type>

Var(TypeVarId)

A type variable introduced during type checking.

Array(Box<Type>)

An array type: [T].

Tuple(Vec<Type>)

A tuple type: (T1, T2, ...).

Implementations

pub fn i32() -> Self

pub fn i64() -> Self

pub fn f64() -> Self

pub fn bool() -> Self

pub fn string() -> Self

pub fn unit() -> Self

Trait Implementations

impl Clone for Type

fn clone(&self) -> Type

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Type

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

Formats the value using the given formatter.

impl PartialEq for Type

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