Struct TypeVarId 

pub struct TypeVarId(pub u32);

A unique handle identifying a type variable. The binding state (Unbound / Bound-to-a-Type) lives in a TypeEnv owned by the checker; the handle is a plain id so Type stays a pure value (Clone, Eq, Hash, Serialize).

Tuple Fields

0: u32

Implementations

impl TypeVarId

pub const IGNORED: TypeVarId

pub const UNINFERRED: TypeVarId

pub fn is_reserved(self) -> bool

pub fn as_u32(self) -> u32

Trait Implementations

impl Clone for TypeVarId

fn clone(&self) -> TypeVarId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TypeVarId

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

Formats the value using the given formatter.

impl Hash for TypeVarId

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 TypeVarId

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