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.

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.
