The Put type
The PutM type. A Writer monad over the efficient Builder monoid.
runPutM :: PutM a -> (a, ByteString) Source #
Run the PutM monad with a serialiser and get its result
putBuilder :: Builder -> Put Source #
Flushing the implicit parse state
Pop the ByteString we have constructed so far, if any, yielding a new chunk in the result ByteString.
Primitives
putByteString :: ByteString -> Put Source #
An efficient primitive to write a strict ByteString into the output buffer. It flushes the current buffer, and writes the argument into a new chunk.
putLazyByteString :: ByteString -> Put Source #
Write a lazy ByteString efficiently, simply appending the lazy ByteString chunks to the output buffer
putShortByteString :: ShortByteString -> Put Source #
Write ShortByteString to the buffer
Big-endian primitives
putWord16be :: Word16 -> Put Source #
Write a Word16 in big endian format
putWord32be :: Word32 -> Put Source #
Write a Word32 in big endian format
putWord64be :: Word64 -> Put Source #
Write a Word64 in big endian format
putInt16be :: Int16 -> Put Source #
Write an Int16 in big endian format
putInt32be :: Int32 -> Put Source #
Write an Int32 in big endian format
putInt64be :: Int64 -> Put Source #
Write an Int64 in big endian format
Little-endian primitives
putWord16le :: Word16 -> Put Source #
Write a Word16 in little endian format
putWord32le :: Word32 -> Put Source #
Write a Word32 in little endian format
putWord64le :: Word64 -> Put Source #
Write a Word64 in little endian format
putInt16le :: Int16 -> Put Source #
Write an Int16 in little endian format
putInt32le :: Int32 -> Put Source #
Write an Int32 in little endian format
putInt64le :: Int64 -> Put Source #
Write an Int64 in little endian format
Host-endian, unaligned writes
putWordhost :: Word -> Put Source #
O(1). Write a single native machine word. The word is written in host order, host endian form, for the machine you're on. On a 64 bit machine the Word is an 8 byte value, on a 32 bit machine, 4 bytes. Values written this way are not portable to different endian or word sized machines, without conversion.
putWord16host :: Word16 -> Put Source #
O(1). Write a Word16 in native host order and host endianness.
For portability issues see putWordhost.
putWord32host :: Word32 -> Put Source #
O(1). Write a Word32 in native host order and host endianness.
For portability issues see putWordhost.
putWord64host :: Word64 -> Put Source #
O(1). Write a Word64 in native host order
On a 32 bit machine we write two host order Word32s, in big endian form.
For portability issues see putWordhost.
putInthost :: Int -> Put Source #
O(1). Write a single native machine word. The word is written in host order, host endian form, for the machine you're on. On a 64 bit machine the Int is an 8 byte value, on a 32 bit machine, 4 bytes. Values written this way are not portable to different endian or word sized machines, without conversion.
putInt16host :: Int16 -> Put Source #
O(1). Write an Int16 in native host order and host endianness.
For portability issues see putInthost.
putInt32host :: Int32 -> Put Source #
O(1). Write an Int32 in native host order and host endianness.
For portability issues see putInthost.
putInt64host :: Int64 -> Put Source #
O(1). Write an Int64 in native host order
On a 32 bit machine we write two host order Int32s, in big endian form.
For portability issues see putInthost.
Unicode
putCharUtf8 :: Char -> Put Source #
Write a character using UTF-8 encoding.
putStringUtf8 :: String -> Put Source #
Write a String using UTF-8 encoding.
