Variants§
ExternCrate(Option<Symbol>)
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(&'hir UsePath<'hir>, UseKind)
use foo::bar::*;
or use foo::bar::baz as quux;
or just
use foo::bar::baz;
(with as baz
implicitly on the right).
Static(&'hir Ty<'hir>, Mutability, BodyId)
A static
item.
Const(&'hir Ty<'hir>, &'hir Generics<'hir>, BodyId)
A const
item.
Fn(FnSig<'hir>, &'hir Generics<'hir>, BodyId)
A function declaration.
Macro(&'hir MacroDef, MacroKind)
A MBE macro definition (macro_rules!
or macro
).
Mod(&'hir Mod<'hir>)
A module.
ForeignMod
An external module, e.g. extern { .. }
.
GlobalAsm(&'hir InlineAsm<'hir>)
Module-level inline assembly (from global_asm!
).
TyAlias(&'hir Ty<'hir>, &'hir Generics<'hir>)
A type alias, e.g., type Foo = Bar<u8>
.
OpaqueTy(&'hir OpaqueTy<'hir>)
An opaque impl Trait
type alias, e.g., type Foo = impl Bar;
.
Enum(EnumDef<'hir>, &'hir Generics<'hir>)
An enum definition, e.g., enum Foo<A, B> {C<A>, D<B>}
.
Struct(VariantData<'hir>, &'hir Generics<'hir>)
A struct definition, e.g., struct Foo<A> {x: A}
.
Union(VariantData<'hir>, &'hir Generics<'hir>)
A union definition, e.g., union Foo<A, B> {x: A, y: B}
.
Trait(IsAuto, Unsafety, &'hir Generics<'hir>, GenericBounds<'hir>, &'hir [TraitItemRef])
A trait definition.
TraitAlias(&'hir Generics<'hir>, GenericBounds<'hir>)
A trait alias.
Impl(&'hir Impl<'hir>)
An implementation, e.g., impl<A> Trait for Foo { .. }
.

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
