[−][src]Enum syntax::ast::TyKind
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
).
Rptr(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(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.
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 NodeId
s on the fly, which would complicate
the generation of existential type
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.
Mac(Mac)
A macro in the type position.
Err
Placeholder for a kind that has failed to be defined.
CVarArgs
Placeholder for a va_list
.
