The various kinds of type recognized by the compiler.

Variants

Slice(P<Ty>)

A variable-length slice ([T]).

Array(P<Ty>, AnonConst)

A fixed length array ([T; n]).

Ptr(MutTy)

A raw pointer (*const T or *mut T).

A reference (&'a T or &'a mut T).

BareFn(P<BareFnTy>)

A bare function (e.g., fn(usize) -> bool).

Never

The never type (!).

Tup(Vec<P<Ty>>)

A tuple ((A, B, C, D,...)).

Path(Option<QSelf>, Path)

A path (module::module::...::Type), optionally "qualified", e.g., <Vec<T> as SomeTrait>::SomeType.

Type parameters are stored in the Path itself.

A trait object type Bound1 + Bound2 + Bound3 where Bound is a trait or a lifetime.

ImplTrait(NodeId, GenericBounds)

An impl Bound1 + Bound2 + Bound3 type where Bound is a trait or a lifetime.

The NodeId exists to prevent lowering from having to generate NodeIds on the fly, which would complicate the generation of opaque type Foo = impl Trait items significantly.

Paren(P<Ty>)

No-op; kept solely so that we can pretty-print faithfully.

Typeof(AnonConst)

Unused for now.

Infer

This means the type should be inferred instead of it having been specified. This can appear anywhere in a type.

ImplicitSelf

Inferred type of a self or &self argument in a method.

MacCall(MacCall)

A macro in the type position.

Err

Placeholder for a kind that has failed to be defined.

CVarArgs

Placeholder for a va_list.

Methods

impl TyKind[src]

pub fn is_implicit_self(&self) -> bool[src]

pub fn is_unit(&self) -> bool[src]

pub fn opaque_top_hack(&self) -> Option<&GenericBounds>[src]

HACK(type_alias_impl_trait, Centril): A temporary crutch used in lowering to avoid making larger changes there and beyond.
