pattern SimpleBind :: Pattern -> Rhs -> MaybeLocalBinds -> ValueBind Source #
Non-function binding ( v = "12" )
pattern FunctionBind :: MatchList -> ValueBind Source #
Function binding ( f 0 = 1; f x = x ). All matches must have the same name.
pattern MatchLhs :: Name -> PatternList -> MatchLhs Source #
A match lhs with the function name and parameter names ( f a b )
pattern InfixLhs :: Pattern -> Operator -> Pattern -> PatternList -> MatchLhs Source #
An infix match lhs for an operator ( a + b )
pattern LocalBinds :: LocalBindList -> LocalBinds Source #
Local bindings attached to a declaration ( where x = 42 )
pattern LocalValBind :: ValueBind -> LocalBind Source #
A local binding for a value
pattern LocalTypeSig :: TypeSignature -> LocalBind Source #
A local type signature
pattern LocalFixity :: FixitySignature -> LocalBind Source #
A local fixity declaration
pattern TypeSignature :: NameList -> Type -> TypeSignature Source #
A type signature ( f :: Int -> Int )
pattern InfixL :: OperatorList -> FixitySignature Source #
A left-associative fixity declaration ( infixl 5 +, - ).
pattern InfixR :: OperatorList -> FixitySignature Source #
A right-associative fixity declaration ( infixr 5 +, - ).
pattern Infix :: OperatorList -> FixitySignature Source #
A non-associative fixity declaration ( infix 5 +, - ).
pattern UnguardedRhs :: Expr -> Rhs Source #
An unguarded right-hand-side ( = 3 )
pattern GuardedRhss :: GuardedRhsList -> Rhs Source #
An unguarded right-hand-side ( | x == 1 = 3; | otherwise = 4 )
pattern GuardedRhs :: RhsGuardList -> Expr -> GuardedRhs Source #
A guarded right-hand side of a value binding ( | x > 3 = 2 )
pattern GuardBind :: Pattern -> Expr -> RhsGuard Source #
A bind statement in a pattern guard ( Just v <- x )
pattern GuardLet :: LocalBindList -> RhsGuard Source #
A let statement in a pattern guard ( let x = 3 )
pattern GuardCheck :: Expr -> RhsGuard Source #
An expression to check for a pattern guard
