Expand description

The various kinds of type recognized by the compiler.

Variants

Slice(P<Ty>)
Expand description

A variable-length slice ([T]).

Array(P<Ty>, AnonConst)
Expand description

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

Ptr(MutTy)
Expand description

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

Rptr(Option<Lifetime>, MutTy)
Expand description

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

BareFn(P<BareFnTy>)
Expand description

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

Never
Expand description

The never type (!).

Tup(Vec<P<Ty>>)
Expand description

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

Path(Option<QSelf>, Path)
Expand description

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)
Expand description

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

ImplTrait(NodeId, GenericBounds)
Expand description

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>)
Expand description

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

Typeof(AnonConst)
Expand description

Unused for now.

Infer
Expand description

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

ImplicitSelf
Expand description

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

MacCall(MacCall)
Expand description

A macro in the type position.

Err
Expand description

Placeholder for a kind that has failed to be defined.

CVarArgs
Expand description

Placeholder for a va_list.
