Tuples
data Tuple a Source
Untyped representation of nested tuples
Constructors
One a
Tup [Tuple a]
show/hide Instances
showTuple :: Tuple String -> StringSource
Shows a nested tuple in Haskell's tuple syntax (e.g "(a,(b,c))").
tuplePath :: Tuple a -> Tuple [Int]Source

Replaces each element by its path in the tuple tree. For example: 

 tuplePath (Tup [One 'a',Tup [One 'b', One 'c']])
   ==
 Tup [One [0],Tup [One [1,0],One [1,1]]]

data StorableType Source
Representation of storable types (arrays of primitive types). Array size is given as a list of ranged lengths, starting with outermost array level. Primitive types are treated as zero-dimensional arrays.
Constructors
StorableType [Range Length] PrimitiveType
show/hide Instances
showPrimitiveRange :: PrimitiveType -> StringSource
showStorableSize :: StorableType -> StringSource
Shows the size of a storable type.
class Storable a => Primitive a Source
Primitive types
show/hide Instances
class Typeable a => Storable a whereSource
Storable types (zero- or higher-level arrays of primitive data).
Methods
storableData :: a -> StorableDataSource
Converts a storable value to its untyped representation.
storableType :: Size a -> T a -> StorableTypeSource
Gives the type representation of a storable value.
storableSize :: a -> Size aSource
Gives the size of a storable value.
listSize :: T a -> Size a -> [Range Length]Source
show/hide Instances
class (Eq a, Monoid (Size a), Set (Size a)) => Typeable a whereSource
Associated Types
type Size a Source
This type provides the necessary extra information to compute a type representation Tuple StorableType from a type a. This is needed because the type a is missing information about sizes of arrays and primitive values.
Methods
typeOf :: Size a -> T a -> Tuple StorableTypeSource
Gives the type representation of a storable value.
show/hide Instances
typeOfStorable :: Storable a => Size a -> T a -> Tuple StorableTypeSource
Default implementation of typeOf for Storable types.
