Structs

AngleBracketedParameterData	A path like `Foo<'a, T>`
Attribute	Doc-comments are promoted to attributes that have `is_sugared_doc` = true
BareFnTy
Discriminant
Field
FnArg	An argument in a function header.
FnDecl	Header (not the body) of a function declaration.
Generics	Represents lifetimes and type parameters attached to a declaration of a function, enum, trait, etc.
Ident
Lifetime
LifetimeDef	A lifetime definition, e.g. `'a: 'b+'c+'d`
MacroInput
MutTy
ParenthesizedParameterData	A path like `Foo(A,B) -> C`
Path	A "Path" is essentially Rust's notion of a name.
PathSegment	A segment of a path: an identifier, an optional lifetime, and a set of types.
PolyTraitRef
QSelf	The explicit Self type in a "qualified path". The actual path, including the trait and the associated item, is stored separately. `position` represents the index of the associated item qualified with this Self type.
TyParam
TypeBinding	Bind a type to an associated type: `A=Foo`.
Variant
WhereBoundPredicate	A type bound.
WhereClause	A `where` clause in a definition
WhereRegionPredicate	A lifetime predicate.

Body
FloatTy
FunctionRetTy
IntTy
Lit	Literal kind.
MetaItem	A compile-time attribute item.
Mutability
PathParameters	Parameters of a path segment.
StrStyle
TraitBoundModifier	A modifier on a bound, currently this is only used for `?Sized`, where the modifier is `Maybe`. Negative bounds should also be handled here.
Ty	The different kinds of types recognized by the compiler
TyParamBound	The AST represents all type param bounds as types. `typeck::collect::compute_bounds` matches these against the "special" built-in traits (see `middle::lang_items`) and detects Copy, Send and Sync.
VariantData
Visibility
WherePredicate	A single predicate in a `where` clause
