Variants

ExternCrate(Option<Name>)

An extern crate item, with optional original crate name if the crate was renamed.

E.g. extern crate foo or extern crate foo_bar as foo

Use(P<UseTree>)

A use declaration (use or pub use) item.

E.g. use foo;, use foo::bar; or use foo::bar as FooBar;

Static(P<Ty>, Mutability, P<Expr>)

A static item (static or pub static).

E.g. static FOO: i32 = 42; or static FOO: &'static str = "bar";

Const(P<Ty>, P<Expr>)

A constant item (const or pub const).

E.g. const FOO: i32 = 42;

Fn(P<FnDecl>, FnHeader, Generics, P<Block>)

A function declaration (fn or pub fn).

E.g. fn foo(bar: usize) -> usize { .. }

Mod(Mod)

A module declaration (mod or pub mod).

E.g. mod foo; or mod foo { .. }

ForeignMod(ForeignMod)

An external module (extern or pub extern).

E.g. extern {} or extern "C" {}

GlobalAsm(P<GlobalAsm>)

Module-level inline assembly (from global_asm!())

Ty(P<Ty>, Generics)

A type alias (type or pub type).

E.g. type Foo = Bar<u8>;

Existential(GenericBounds, Generics)

An existential type declaration (existential type).

E.g. existential type Foo: Bar + Boo;

Enum(EnumDef, Generics)

An enum definition (enum or pub enum).

E.g. enum Foo<A, B> { C<A>, D<B> }

Struct(VariantData, Generics)

A struct definition (struct or pub struct).

E.g. struct Foo<A> { x: A }

Union(VariantData, Generics)

A union definition (union or pub union).

E.g. union Foo<A, B> { x: A, y: B }

Trait(IsAuto, Unsafety, Generics, GenericBounds, Vec<TraitItem>)

A Trait declaration (trait or pub trait).

E.g. trait Foo { .. }, trait Foo<T> { .. } or auto trait Foo {}

TraitAlias(Generics, GenericBounds)

Trait alias

E.g. trait Foo = Bar + Quux;

Impl(Unsafety, ImplPolarity, Defaultness, Generics, Option<TraitRef>, P<Ty>, Vec<ImplItem>)

An implementation.

E.g. impl<A> Foo<A> { .. } or impl<A> Trait for Foo<A> { .. }

Mac(Mac)

A macro invocation.

E.g. macro_rules! foo { .. } or foo!(..)

MacroDef(MacroDef)

A macro definition.
