valueunsafeReadIOArray :: IOArray i e -> Int -> IO e

Read a value from an IOArray

valueunsafeWriteIOArray :: IOArray i e -> Int -> e -> IO ()

Write a new value into an IOArray

valuereadIOArray :: Ix i => IOArray i e -> i -> IO e

Read a value from an IOArray

valuewriteIOArray :: Ix i => IOArray i e -> i -> e -> IO ()
