GHC.Iface.Type

Synopsis

Documentation

data IfaceType Source #

A kind of universal type, used for types and kinds.

Any time a Type is pretty-printed, it is first converted to an IfaceType before being printed. See Note [Pretty printing via Iface syntax] in GHC.Types.TyThing.Ppr

data IfaceTyConSort Source #

The various types of TyCons which have special, built-in syntax.

Constructors

IfaceNormalTyCon

a regular tycon

IfaceTupleTyCon !Arity !TupleSort

a tuple, e.g. (a, b, c) or (#a, b, c#). The arity is the tuple width, not the tycon arity (which is twice the width in the case of unboxed tuples).

IfaceSumTyCon !Arity

an unboxed sum, e.g. (# a | b | c #)

IfaceEqualityTyCon

A heterogeneous equality TyCon (i.e. eqPrimTyCon, eqReprPrimTyCon, heqTyCon) that is actually being applied to two types of the same kind. This affects pretty-printing only: see Note [Equality predicates in IfaceType]

data FunTyFlag Source #

The non-dependent version of ForAllTyFlag. See Note [FunTyFlag] Appears here partly so that it's together with its friends ForAllTyFlag and ForallVisFlag, but also because it is used in IfaceType, rather early in the compilation chain

data ShowForAllFlag Source #

Show forall flag

Unconditionally show the forall quantifier with (ShowForAllMust) or when (ShowForAllWhen) the names used are free in the binder or when compiling with -fprint-explicit-foralls.

mkIfaceTyConKind :: [IfaceTyConBinder] -> IfaceKind -> IfaceKind Source #

Build the tyConKind from the binders and the result kind. Keep in sync with mkTyConKind in GHC.Core.TyCon.

ifForAllBndrName :: IfaceForAllBndr -> IfLclName Source #

Extract the variable name from an IfaceForAllBndr.

ifTyConBinderName :: IfaceTyConBinder -> IfLclName Source #

Extract the variable name from an IfaceTyConBinder.

isIfaceLiftedTypeKind :: IfaceKind -> Bool Source #

Returns true for Type or (TYPE LiftedRep)

pprIfaceContext :: PprPrec -> [IfacePredType] -> SDoc Source #

Prints a context or () if empty You give it the context precedence

pprIfaceContextArr :: [IfacePredType] -> SDoc Source #

Prints "(C a, D b) =>", including the arrow. Used when we want to print a context in a type, so we use funPrec to decide whether to parenthesise a singleton predicate; e.g. Num a => a -> a

pprIfaceForAllPartMust :: [IfaceForAllBndr] -> [IfacePredType] -> SDoc -> SDoc Source #

Like pprIfaceForAllPart, but always uses an explicit forall.

pprIfaceForAll :: [IfaceForAllBndr] -> SDoc Source #

Render the "forall ... ." or "forall ... ->" bit of a type.

mkIfaceTySubst :: [(IfLclName, IfaceType)] -> IfaceTySubst Source #

inDomIfaceTySubst :: IfaceTySubst -> IfaceTvBndr -> Bool Source #

many_ty :: IfaceType Source #
