Expand description

The possible types that a Rust value could have.

§Syntax tree enum

This type is a syntax tree enum.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Array(TypeArray)

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

BareFn(TypeBareFn)

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

Group(TypeGroup)

A type contained within invisible delimiters.

ImplTrait(TypeImplTrait)

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

Infer(TypeInfer)

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

Macro(TypeMacro)

A macro in the type position.

Never(TypeNever)

The never type: !.

Paren(TypeParen)

A parenthesized type equivalent to the inner type.

Path(TypePath)

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

Ptr(TypePtr)

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

Reference(TypeReference)

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

Slice(TypeSlice)

A dynamically sized slice type: [T].

TraitObject(TypeTraitObject)

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

Tuple(TypeTuple)

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

Verbatim(TokenStream)

Tokens in type position not interpreted by Syn.

Implementations§

impl Type

pub fn without_plus(input: &ParseBuffer<'_>) -> Result<Type, Error>

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.

painted.quirk(Quirk::Wrap);

Enable wrapping using wrap().
