Type of a struct field or tuple variant field in the syntax tree.

Variants

Syn(String)

Syntax tree type defined by Syn.

This name will match the ident of some Node.

Std(String)

Type defined by the Rust language or standard library.

All such types used by Syn are accessible in the Rust prelude and can be used without a qualifying path in most Rust code.

Ext(String)

Type defined by proc-macro2.

The type is accessible in the proc-macro2 public API as proc_macro2::#name.

Token(String)

Keyword or punctuation token type defined by Syn.

This name will match one of the keys in the tokens map.

Group(String)

Grouping token defined by Syn.

The type is accessible in the Syn public API as syn::token::#name.

Punctuated(Punctuated)

Punctuated list.

This refers to syn::punctuated::Punctuated<T, P> with the specified element type and punctuation.

Option(Box<Type>)

std::option::Option

Box(Box<Type>)

std::boxed::Box

Vec(Box<Type>)

std::vec::Vec

Tuple(Vec<Type>)

Rust tuple with two or more fields.

Trait Implementations

impl Clone for Type

fn clone(&self) -> Type

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Type

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Type

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Type

fn eq(&self, other: &Type) -> bool

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Type

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
