-- | A globally unique fresh identifier supply with local pooling and
--   replay support.
module Control.Concurrent.Supply

-- | A user managed globally unique variable supply.
data Supply

-- | Grab a new supply. Any two supplies obtained with newSupply are
--   guaranteed to return disjoint sets of identifiers. Replaying the same
--   sequence of operations on the same Supply will yield the same results.
newSupply :: IO Supply

-- | Obtain a fresh Id from a Supply.
freshId :: Supply -> (Int, Supply)

-- | Split a supply into two supplies that will return disjoint identifiers
splitSupply :: Supply -> (Supply, Supply)

-- | An unboxed version of freshId
freshId# :: Supply -> (# Int#, Supply #)

-- | An unboxed version of splitSupply
