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 (). 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 #
