data HsLit x Source #

Haskell Literal

Constructors

HsChar (XHsChar x) Char	Character
HsCharPrim (XHsCharPrim x) Char	Unboxed character
HsString (XHsString x) FastString	String
HsStringPrim (XHsStringPrim x) !ByteString	Packed bytes
HsInt (XHsInt x) IntegralLit	Genuinely an Int; arises from GHC.Tc.Deriv.Generate, and from TRANSLATION
HsIntPrim (XHsIntPrim x) Integer	literal `Int#`
HsWordPrim (XHsWordPrim x) Integer	literal `Word#`
HsInt64Prim (XHsInt64Prim x) Integer	literal `Int64#`
HsWord64Prim (XHsWord64Prim x) Integer	literal `Word64#`
HsInteger (XHsInteger x) Integer Type	Genuinely an integer; arises only from TRANSLATION (overloaded literals are done with HsOverLit)
HsRat (XHsRat x) FractionalLit Type	Genuinely a rational; arises only from TRANSLATION (overloaded literals are done with HsOverLit)
HsFloatPrim (XHsFloatPrim x) FractionalLit	Unboxed Float
