Expand description

The various kinds of types recognized by the compiler.

Variants

Slice(&'hir Ty<'hir>)
Expand description

A variable length slice (i.e., [T]).

Array(&'hir Ty<'hir>, AnonConst)
Expand description

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

Ptr(MutTy<'hir>)
Expand description

A raw pointer (i.e., *const T or *mut T).

Rptr(Lifetime, MutTy<'hir>)
Expand description

A reference (i.e., &'a T or &'a mut T).

BareFn(&'hir BareFnTy<'hir>)
Expand description

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

Never
Expand description

The never type (!).

Tup(&'hir [Ty<'hir>])
Expand description

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

Path(QPath<'hir>)
Expand description

A path to a type definition (module::module::...::Type), or an associated type (e.g., <Vec<T> as Trait>::Type or <T>::Target).

Type parameters may be stored in each PathSegment.

OpaqueDef(ItemId, &'hir [GenericArg<'hir>])
Expand description

A opaque type definition itself. This is currently only used for the opaque type Foo: Trait item that impl Trait in desugars to.

The generic argument list contains the lifetimes (and in the future possibly parameters) that are actually bound on the impl Trait.

TraitObject(&'hir [PolyTraitRef<'hir>], Lifetime, TraitObjectSyntax)
Expand description

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

Typeof(AnonConst)
Expand description

Unused for now.

Infer
Expand description

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

Err
Expand description

Placeholder for a type that has failed to be defined.
