Expand description

The possible types that a Rust value could have.

This type is available if Syn is built with the "derive" or "full" feature.

Syntax tree enum

This type is a syntax tree enum.

Variants

Slice(TypeSlice)

A dynamically sized slice type: [T].

This type is available if Syn is built with the "derive" or "full" feature.

Tuple Fields of Slice

0: TypeSlice
Array(TypeArray)

A fixed size array type: [T; n].

This type is available if Syn is built with the "derive" or "full" feature.

Tuple Fields of Array

0: TypeArray
Ptr(TypePtr)

A raw pointer type: *const T or *mut T.

This type is available if Syn is built with the "derive" or "full" feature.

Tuple Fields of Ptr

0: TypePtr
Reference(TypeReference)

A reference type: &'a T or &'a mut T.

This type is available if Syn is built with the "derive" or "full" feature.

Tuple Fields of Reference

0: TypeReference
BareFn(TypeBareFn)

A bare function type: fn(usize) -> bool.

This type is available if Syn is built with the "derive" or "full" feature.

Tuple Fields of BareFn

0: TypeBareFn
Never(TypeNever)

The never type: !.

This type is available if Syn is built with the "derive" or "full" feature.

Tuple Fields of Never

0: TypeNever
Tuple(TypeTuple)

A tuple type: (A, B, C, String).

This type is available if Syn is built with the "derive" or "full" feature.

Tuple Fields of Tuple

0: TypeTuple
Path(TypePath)

A path like std::slice::Iter, optionally qualified with a self-type as in <Vec<T> as SomeTrait>::Associated.

Type arguments are stored in the Path itself.

This type is available if Syn is built with the "derive" or "full" feature.

Tuple Fields of Path

0: TypePath
TraitObject(TypeTraitObject)

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

This type is available if Syn is built with the "derive" or "full" feature.

Tuple Fields of TraitObject

0: TypeTraitObject
ImplTrait(TypeImplTrait)

An impl Bound1 + Bound2 + Bound3 type where Bound is a trait or a lifetime.

This type is available if Syn is built with the "derive" or "full" feature.

Tuple Fields of ImplTrait

0: TypeImplTrait
Paren(TypeParen)

A parenthesized type equivalent to the inner type.

This type is available if Syn is built with the "derive" or "full" feature.

Tuple Fields of Paren

0: TypeParen
Group(TypeGroup)

A type contained within invisible delimiters.

This type is available if Syn is built with the "derive" or "full" feature.

Tuple Fields of Group

0: TypeGroup
Infer(TypeInfer)

Indication that a type should be inferred by the compiler: _.

This type is available if Syn is built with the "derive" or "full" feature.

Tuple Fields of Infer

0: TypeInfer
Macro(TypeMacro)

A macro in the type position.

This type is available if Syn is built with the "derive" or "full" feature.

Tuple Fields of Macro

0: TypeMacro
Verbatim(TypeVerbatim)

Tokens in type position not interpreted by Syn.

This type is available if Syn is built with the "derive" or "full" feature.

Tuple Fields of Verbatim

0: TypeVerbatim

Implementations

In some positions, types may not contain the + character, to disambiguate them. For example in the expression 1 as T, T may not contain a + character.

This parser does not allow a +, while the default parser does.
