Documentation

type IfExtName = Name Source #

type IfLclName = FastString Source #

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]
