Documentation
Use this type to mark a Haskell function definition as a Rattus function:
{-# ANN myFunction Rattus #-}
Or mark a whole module as consisting of Rattus functions only:
{-# ANN module Rattus #-}
If you use the latter option, you can mark exceptions (i.e. functions that should be treated as ordinary Haskell function definitions) as follows:
{-# ANN myFunction NotRattus #-}
By default all Rattus functions are checked for use of lazy data
types, since these may cause memory leaks. If any lazy data types
are used, a warning is issued. These warnings can be disabled by
annotating the module or the function with AllowLazyData
{-# ANN myFunction AllowLazyData #-} {-# ANN module AllowLazyData #-}
Rattus only allows guarded recursion, i.e. recursive calls must
occur in the scope of a tick. Structural recursion over strict data
types is safe as well, but is currently not checked. To disable the
guarded recursion check, annotate the module or function with
AllowRecursion
.
