1. readTVarIO :: TVar a -> IO a

   rebase	Rebase.Prelude

   Return the current value stored in a TVar. This is equivalent to

   readTVarIO = atomically . readTVar
   

   but works much faster, because it doesn't perform a complete transaction, it just reads the current value of the TVar.

2. stateTVar :: TVar s -> (s -> (a, s)) -> STM a

   rebase	Rebase.Prelude

   Like modifyTVar' but the function is a simple state transition that can return a side value which is passed on as the result of the STM.

3. swapTVar :: TVar a -> a -> STM a

   rebase	Rebase.Prelude

   Swap the contents of a TVar for a new value.

4. writeTVar :: TVar a -> a -> STM ()

   rebase	Rebase.Prelude

   Write the supplied value into a TVar.

5. getVarNames :: Data a => a -> [Name]

   store	Data.Store.TypeHash.Internal

   No documentation available.

6. optVariableWeighting :: CollatorOptions -> VariableWeighting

   unicode-collation	Text.Collate

   Method for handling variable elements (see http://www.unicode.org/reports/tr10/, Tables 11 and 12).

7. setVariableWeighting :: VariableWeighting -> Collator -> Collator

   unicode-collation	Text.Collate

   Set method for handling variable elements (punctuation and spaces): see http://www.unicode.org/reports/tr10/, Tables 11 and 12.

8. newTVar :: a -> STM (TVar a)

   base-prelude	BasePrelude

   Create a new TVar holding a value supplied

9. newTVarIO :: a -> IO (TVar a)

   base-prelude	BasePrelude

   IO version of newTVar. This is useful for creating top-level TVars using unsafePerformIO, because using atomically inside unsafePerformIO isn't possible.

10. readTVar :: TVar a -> STM a

    base-prelude	BasePrelude

    Return the current value stored in a TVar.
