Instances

Monad Fay Source #
Methods (>>=) :: Fay a -> (a -> Fay b) -> Fay b # (>>) :: Fay a -> Fay b -> Fay b # return :: a -> Fay a # fail :: String -> Fay a #
Functor Fay Source #
Methods fmap :: (a -> b) -> Fay a -> Fay b # (<$) :: a -> Fay b -> Fay a #
Applicative Fay Source #
Methods pure :: a -> Fay a # (<>) :: Fay (a -> b) -> Fay a -> Fay b # liftA2 :: (a -> b -> c) -> Fay a -> Fay b -> Fay c # (>) :: Fay a -> Fay b -> Fay b # (<*) :: Fay a -> Fay b -> Fay a #

Values that may be null Nullable x decodes to x, Null decodes to null.

Constructors

Nullable a
Null

Values that may be undefined Defined x encodes to x, Undefined decodes to undefined. An undefined property in a record will be removed when encoding.

Constructors

Defined a
Undefined

type Ptr a = a Source #

Do not serialize the specified type. This is useful for, e.g.

foo :: String -> String
foo = ffi "%1"

This would normally serialize and unserialize the string, for no reason, in this case. Instead:

foo :: Ptr String -> Ptr String

Will just give an identity function.

The opposite of Ptr. Serialize the specified polymorphic type.

foo :: Automatic a -> String

Arguments

Declare a foreign action.
