Exact lookup

1. read :: InputStream a -> IO (Maybe a)

   io-streams	System.IO.Streams.Internal

   Reads one value from an InputStream. Returns either a value wrapped in a Just, or Nothing if the end of the stream is reached.

2. read :: Read a => String -> a

   rio	RIO.Partial

   The read function reads input from a string, which must be completely consumed by the input process. read fails with an error if the parse is unsuccessful, and it is therefore discouraged from being used in real applications. Use readMaybe or readEither for safe alternatives.

   >>> read "123" :: Int
   123
   

   >>> read "hello" :: Int
   *** Exception: Prelude.read: no parse
   

3. read :: SSL -> Int -> IO ByteString

   HsOpenSSL	OpenSSL.Session

   Try to read the given number of bytes from an SSL connection. On EOF an empty ByteString is returned. If the connection dies without a graceful SSL shutdown, an exception is raised. NOTE: The returned bytestring could be shorter than the size requested, see: https://www.openssl.org/docs/man3.0/man3/SSL_read.html

4. read :: Storable e => Vector s e -> Int -> ST s e

   storablevector	Data.StorableVector.ST.Lazy

   Control.Monad.ST.runST (do arr <- new_ 10; Monad.zipWithM_ (write arr) [9,8..0] ['a'..]; read arr 3)
   

5. read :: Storable e => Vector s e -> Int -> ST s e

   storablevector	Data.StorableVector.ST.Strict

   Control.Monad.ST.runST (do arr <- new_ 10; Monad.zipWithM_ (write arr) [9,8..0] ['a'..]; read arr 3)
   

6. read :: (PrimMonad m, Indexed sh, Storable a) => Array m sh a -> Index sh -> m a

   comfort-array	Data.Array.Comfort.Storable.Mutable

   No documentation available.

7. read :: (PrimMonad m, Indexed sh, Storable a) => Array m sh a -> Index sh -> m a

   comfort-array	Data.Array.Comfort.Storable.Mutable.Private

   No documentation available.

8. read :: (PrimMonad m, Indexed sh, Storable a) => Array m sh a -> Index sh -> m a

   comfort-array	Data.Array.Comfort.Storable.Mutable.Unchecked

   No documentation available.

9. read :: Read a => String -> a

   relude	Relude.Unsafe

   The read function reads input from a string, which must be completely consumed by the input process. read fails with an error if the parse is unsuccessful, and it is therefore discouraged from being used in real applications. Use readMaybe or readEither for safe alternatives.

   >>> read "123" :: Int
   123
   

   >>> read "hello" :: Int
   *** Exception: Prelude.read: no parse
   

10. read :: forall (m :: Type -> Type) a r . (Monad m, Read a) => Stream (Of String) m r -> Stream (Of a) m r

    streaming	Streaming.Prelude

    Make a stream of strings into a stream of parsed values, skipping bad cases

    >>> S.sum_ $ S.read $ S.takeWhile (/= "total") S.stdinLn :: IO Int
    1000<Enter>
    2000<Enter>
    total<Enter>
    3000
