Expand description

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).

§

Ref(Option<Lifetime>, MutTy)

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

§

BareFn(P<BareFnTy>)

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

§

Never

The never type (!).

§

Tup(ThinVec<P<Ty>>)

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

§

AnonStruct(NodeId, ThinVec<FieldDef>)

An anonymous struct type i.e. struct { foo: Type }

§

AnonUnion(NodeId, ThinVec<FieldDef>)

An anonymous union type i.e. union { bar: Type }

§

Path(Option<P<QSelf>>, Path)

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

Type parameters are stored in the Path itself.

§

TraitObject(GenericBounds, TraitObjectSyntax)

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(P<MacCall>)

A macro in the type position.

§

CVarArgs

Placeholder for a va_list.

§

Dummy

Sometimes we need a dummy value when no error has occurred.

§

Err(ErrorGuaranteed)

Placeholder for a kind that has failed to be defined.
