The different kinds of types recognized by the compiler

Variants

TyVec(P<Ty>)TyFixedLengthVec(P<Ty>, P<Expr>)

A fixed length array ([T; n])

TyPtr(MutTy)

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

TyRptr(Option<Lifetime>, MutTy)

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

TyBareFn(P<BareFnTy>)

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

TyTup(Vec<P<Ty>>)

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

TyPath(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

TyObjectSum(P<Ty>, TyParamBounds)

Something like A+B. Note that B must always be a path.

TyPolyTraitRef(TyParamBounds)

A type like for<'a> Foo<&'a Bar>

TyParen(P<Ty>)

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

TyTypeof(P<Expr>)

Unused for now

TyInfer

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

TyMac(Mac)

Trait Implementations

impl Debug for Ty_

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Hash for Ty_

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the state given, updating the hasher as necessary.

fn hash_slice<H>(data: &[Self], state: &mut H) where H: Hasher

Feeds a slice of this type into the state provided.

impl Decodable for Ty_

fn decode<__D: Decoder>(__arg_0: &mut __D) -> Result<Ty_, __D::Error>

impl Encodable for Ty_

fn encode<__S: Encoder>(&self, __arg_0: &mut __S) -> Result<(), __S::Error>

impl Eq for Ty_

impl PartialEq for Ty_

fn eq(&self, __arg_0: &Ty_) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &Ty_) -> bool

This method tests for !=.

impl Clone for Ty_

fn clone(&self) -> Ty_

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
