1. readPixel :: (Pixel a, PrimMonad m) => MutableImage (PrimState m) a -> Int -> Int -> m a

   JuicyPixels	Codec.Picture.Types

   Same as pixelAt but for mutable images.

2. readChunk :: ReadHandle -> IO ByteString

   streaming-commons	Data.Streaming.FileRead

   No documentation available.

3. readDirStream :: DirStream -> IO (Maybe FilePath)

   streaming-commons	Data.Streaming.Filesystem

   No documentation available.

4. readBufferSizeLens :: (HasReadBufferSize a, Functor f) => (Int -> f Int) -> a -> f a

   streaming-commons	Data.Streaming.Network

   No documentation available.

5. readLens :: (HasReadWrite a, Functor f) => (IO ByteString -> f (IO ByteString)) -> a -> f a

   streaming-commons	Data.Streaming.Network

   No documentation available.

6. reader :: MonadReader r m => (r -> a) -> m a

   adjunctions	Control.Monad.Representable.Reader

   Retrieves a function of the current environment.

7. readerT :: forall (f :: Type -> Type) m b . Representable f => (Rep f -> m b) -> ReaderT f m b

   adjunctions	Control.Monad.Representable.Reader

   No documentation available.

8. readWord8 :: ByteSource source => source Word8

   data-accessor	Data.Accessor.BinaryRead

   No documentation available.

9. readProcess :: MonadIO m => ProcessConfig stdin stdoutIgnored stderrIgnored -> m (ExitCode, ByteString, ByteString)

   typed-process	System.Process.Typed

   Run a process, capture its standard output and error as a ByteString, wait for it to complete, and then return its exit code, output, and error. Note that any previously used setStdout or setStderr will be overridden.

10. readProcessInterleaved :: MonadIO m => ProcessConfig stdin stdoutIgnored stderrIgnored -> m (ExitCode, ByteString)

    typed-process	System.Process.Typed

    Same as readProcess, but interleaves stderr with stdout. Motivation: Use this function if you need stdout interleaved with stderr output (e.g. from an HTTP server) in order to debug failures.
