Variants

ExternCrate(Option<Name>)

An extern crate item, with the 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 item (use).

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

Static(P<Ty>, Mutability, P<Expr>)

A static item (static).

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

Const(P<Ty>, P<Expr>)

A constant item (const).

E.g., const FOO: i32 = 42;.

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

A function declaration (fn).

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

Mod(Mod)

A module declaration (mod).

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

ForeignMod(ForeignMod)

An external module (extern).

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

GlobalAsm(P<GlobalAsm>)

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

TyAlias(P<Ty>, Generics)

A type alias (type).

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

OpaqueTy(GenericBounds, Generics)

An opaque impl Trait type alias.

E.g., type Foo = impl Bar + Boo;.

Enum(EnumDef, Generics)

An enum definition (enum).

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

Struct(VariantData, Generics)

A struct definition (struct).

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

Union(VariantData, Generics)

A union definition (union).

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

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

A trait declaration (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., foo!(..).

MacroDef(MacroDef)

A macro definition.
