Specific fields of an item.

Part of Item.

Variants

Module(Module)

A module declaration, e.g. mod foo; or mod foo {}

ExternCrate

A crate imported via the extern crate syntax.

Fields

name: String

The name of the imported crate.

rename: Option<String>

If the crate is renamed, this is its name in the crate.

Use(Use)

An import of 1 or more items into scope, using the use keyword.

Union(Union)

A union declaration.

Struct(Struct)

A struct declaration.

StructField(Type)

A field of a struct.

Enum(Enum)

An enum declaration.

Variant(Variant)

A variant of a enum.

Function(Function)

A function declaration (including methods and other associated functions)

Trait(Trait)

A trait declaration.

TraitAlias(TraitAlias)

A trait alias declaration, e.g. trait Int = Add + Sub + Mul + Div;

See the tracking issue

Impl(Impl)

An impl block.

TypeAlias(TypeAlias)

A type alias declaration, e.g. type Pig = std::borrow::Cow<'static, str>;

Constant

The declaration of a constant, e.g. const GREETING: &str = "Hi :3";

Fields

type_: Type

The type of the constant.

const_: Constant

The declared constant itself.

Static(Static)

A declaration of a static.

ExternType

types from an extern block.

See the tracking issue

Macro(String)

A macro_rules! declarative macro. Contains a single string with the source representation of the macro with the patterns stripped.

ProcMacro(ProcMacro)

A procedural macro.

Primitive(Primitive)

A primitive type, e.g. u32.

Items of this kind only come from the core library.

AssocConst

An associated constant of a trait or a type.

Fields

type_: Type

The type of the constant.

value: Option<String>

Inside a trait declaration, this is the default value for the associated constant, if provided. Inside an impl block, this is the value assigned to the associated constant, and will always be present.

The representation is implementation-defined and not guaranteed to be representative of either the resulting value or of the source code.

const X: usize = 640 * 1024;
//               ^^^^^^^^^^

default_unstable: Option<Box<ProvidedDefaultUnstable>>

Metadata about an unstable default value provided for the associated constant, if any.

Empty if the associated constant has no default (see ItemEnum::AssocConst::value), or if the default value is stable.

AssocType

An associated type of a trait or a type.

Fields

generics: Generics

The generic parameters and where clauses on ahis associated type.

bounds: Vec<GenericBound>

The bounds for this associated type. e.g.

trait IntoIterator {
    type Item;
    type IntoIter: Iterator<Item = Self::Item>;
//                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^
}

type_: Option<Type>

Inside a trait declaration, this is the default for the associated type, if provided. Inside an impl block, this is the type assigned to the associated type, and will always be present.

type X = usize;
//       ^^^^^

default_unstable: Option<Box<ProvidedDefaultUnstable>>

Metadata about an unstable default value provided for the associated type, if any.

Empty if the associated type has no default (see ItemEnum::AssocType::type_), or if the default value is stable.

Implementations

impl ItemEnum

pub fn item_kind(&self) -> ItemKind

Get just the kind of this item, but with no further data.

let item = ItemEnum::ExternCrate { name: "libc".to_owned(), rename: None };
assert_eq!(item.item_kind(), ItemKind::ExternCrate);

Trait Implementations

impl Clone for ItemEnum

fn clone(&self) -> ItemEnum

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ItemEnum

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ItemEnum

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ItemEnum

impl Hash for ItemEnum

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ItemEnum

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for ItemEnum

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
