Struct TyVar 

pub struct TyVar {
    pub id: u32,
    pub kind: Kind,
}

A type variable, used for polymorphic types.

Type variables can be either:

• Unification variables: Created during type inference, to be solved
• Rigid variables: Bound by forall quantifiers, cannot be unified

Fields

id: u32

Unique identifier for this type variable.

kind: Kind

The kind of this type variable.

Implementations

impl TyVar

pub fn new(id: u32, kind: Kind) -> Self

Creates a new type variable with the given ID and kind.

pub fn new_star(id: u32) -> Self

Creates a new type variable with kind * (Type).

Trait Implementations

impl Clone for TyVar

fn clone(&self) -> TyVar

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TyVar

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TyVar

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for TyVar

impl Hash for TyVar

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 TyVar

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
