Enum TyKind 

pub enum TyKind {
    Indexed(BaseTy, Expr),
    Exists(Binder<Ty>),
    Constr(Expr, Ty),
    Uninit,
    StrgRef(Region, Path, Ty),
    Ptr(PtrKind, Path),
    Discr(AdtDef, Place),

}

Variants

Indexed(BaseTy, Expr)

Exists(Binder<Ty>)

Constr(Expr, Ty)

Uninit

StrgRef(Region, Path, Ty)

Ptr(PtrKind, Path)

Discr(AdtDef, Place)

This is a bit of a hack. We use this type internally to represent the result of Rvalue::Discriminant in a way that we can recover the necessary control information when checking a match. The hack is that we assume the dicriminant remains the same from the creation of this type until we use it in a match.

Param(ParamTy)

Downcast(AdtDef, GenericArgs, Ty, VariantIdx, List<Ty>)

These only arise when you “narrow” an ADT down to a particular variant; either EXPLICITLY in a match-of, or IMPLICITLY when you access a field of a struct to “UNPACK” the struct.

Blocked(Ty)

Infer(TyVid)

A type that needs to be inferred by matching the signature against a rust signature. TyKind::Infer appear as an intermediate step during conv and should not be present in the final signature.

Implementations

impl TyKind

fn intern(self) -> Ty

Trait Implementations

impl Clone for TyKind

fn clone(&self) -> TyKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TyKind

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

Formats the value using the given formatter.

impl<'tcx, __D: TyDecoder<'tcx>> Decodable<__D> for TyKind

fn decode(__decoder: &mut __D) -> Self

impl<'tcx, __E: TyEncoder<'tcx>> Encodable<__E> for TyKind

fn encode(&self, __encoder: &mut __E)

impl Hash for TyKind

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 Internable for TyKind

fn storage() -> &'static InternStorage<Self>

impl PartialEq for TyKind

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