Crate cpp_syn [] [src]

Modules

parse

This module contains a set of exported nom parsers which can be used to parse custom grammars when used alongside the synom crate.

Macros

add_span
spanned

Structs

AngleBracketedParameterData

A path like Foo<'a, T>

Attribute

Doc-comments are promoted to attributes that have is_sugared_doc = true

BareFnArg

An argument in a function type.

BareFnTy
ByteStrLit
Delimited
DeriveInput
Field
FloatLit
Generics

Represents lifetimes and type parameters attached to a declaration of a function, enum, trait, etc.

Ident
ImplGenerics

Returned by Generics::split_for_impl.

IntLit
Lifetime
LifetimeDef

A lifetime definition, e.g. 'a: 'b+'c+'d

Lit

Literal kind.

Mac

Represents a macro invocation. The Path indicates which macro is being invoked, and the vector of token-trees contains the source of the macro invocation.

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.

Span
Spanned
StrLit
Turbofish

Returned by TyGenerics::as_turbofish.

TyGenerics

Returned by Generics::split_for_impl.

TyParam
TypeBinding

Bind a type to an associated type: A=Foo.

Variant
WhereBoundPredicate

A type bound.

WhereClause

A where clause in a definition

WhereEqPredicate

An equality predicate (unsupported).

WhereRegionPredicate

A lifetime predicate.

Enums

Abi
AttrStyle

Distinguishes between Attributes that decorate items and Attributes that are contained as statements within items. These two cases need to be distinguished for pretty-printing.

BinOp
BinOpToken
Body
ConstExpr
DelimToken

A delimiter token

FloatTy
FunctionRetTy
IntTy
LitKind
MetaItem

A compile-time attribute item.

Mutability
NestedMetaItem

Possible values inside of compile-time attribute lists.

PathParameters

Parameters of a path segment.

StrStyle
Token
TokenTree

When the main rust parser encounters a syntax-extension invocation, it parses the arguments to the invocation as a token-tree. This is a very loose structure, such that all sorts of different AST-fragments can be passed to syntax extensions using a uniform type.

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.

UnOp
Unsafety
VariantData
Visibility
WherePredicate

A single predicate in a where clause

Constants

DUMMY_SPAN
EMPTY_SPAN
