IfaceType

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 IfaceSyn] in PprTyThing

data IfaceTyConSort Source #

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

Constructors

IfaceNormalTyCon

a regular tycon

IfaceTupleTyCon !Arity !TupleSort

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

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]

Constructors

ForallVis

A visible forall (with an arrow)

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 types/TyCon.

ifForAllBndrName :: IfaceForAllBndr -> IfLclName Source #

Extract the variable name from an IfaceForAllBndr.

ifTyConBinderName :: IfaceTyConBinder -> IfLclName Source #

Extract the variable name from an IfaceTyConBinder.

newtype SuppressBndrSig Source #

Do we want to suppress kind annotations on binders? See Note [Suppressing binder signatures]

Constructors

SuppressBndrSig Bool 

newtype UseBndrParens Source #

Constructors

UseBndrParens Bool 

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 #
