hLookAhead :: Handle -> IO Charbase System.IO Computation hLookAhead returns the next character from the handle without removing it from the input buffer, blocking until a character is available. This operation may fail with:
- isEOFError if the end of file has been reached.
hLookAhead :: Handle -> IO Charbase GHC.IO.Handle Computation hLookAhead returns the next character from the handle without removing it from the input buffer, blocking until a character is available. This operation may fail with:

bytestring Data.ByteString.Builder.Internal The memory management overhead. Currently this is tuned for GHC only.

bytestring Data.ByteString.Lazy.Internal The memory management overhead. Currently this is tuned for GHC only.
unsafeHead :: ByteString -> Word8bytestring Data.ByteString.Unsafe A variety of head for non-empty ByteStrings. unsafeHead omits the check for the empty case, so there is an obligation on the programmer to provide a proof that the ByteString is non-empty.
-
text Data.Text.Internal.Lazy The memory management overhead. Currently this is tuned for GHC only.
-
text Data.Text.Unsafe O(1) A variant of head for non-empty Text. unsafeHead omits the check for the empty case, so there is an obligation on the programmer to provide a proof that the Text is non-empty.
