Enum TypeKind 

pub enum TypeKind {
    Var(TypeVar),
    Con(TypeConst),
    App(Type, Type),
    Fun(Type, Type),
    Tuple(Vec<Type>),
    Record(Vec<(Symbol, Type)>),
}

Variants

Var(TypeVar)

Con(TypeConst)

App(Type, Type)

Fun(Type, Type)

Tuple(Vec<Type>)

Record(Vec<(Symbol, Type)>)

Record type {a: T, b: U}.

Invariant: fields are sorted by name. This makes record equality and unification a cheap zip over two vectors, and it makes printing stable.

Trait Implementations

impl AsRef<TypeKind> for Type

fn as_ref(&self) -> &TypeKind

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for TypeKind

fn clone(&self) -> TypeKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TypeKind

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

Formats the value using the given formatter.

impl Hash for TypeKind

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 Ord for TypeKind

fn cmp(&self, other: &TypeKind) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for TypeKind

fn eq(&self, other: &TypeKind) -> 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 PartialOrd for TypeKind

fn partial_cmp(&self, other: &TypeKind) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Eq for TypeKind

impl StructuralPartialEq for TypeKind
