[−][src]Enum syn::Type
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
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 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
[src]
pub fn without_plus(input: ParseStream) -> Result<Self>
[src]
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.
