Description

This module generalizes the binary PutM and cereal PutM monads in an ad hoc fashion to permit code to be written that is compatible across them.

Moreover, this class permits code to be written to be portable over various monad transformers applied to these as base monads.

Synopsis

class (Applicative m, Monad m) => MonadPut m where Source

Minimal complete definition

Nothing

Methods

putWord8 :: Word8 -> m () Source

Efficiently write a byte into the output buffer

putByteString :: ByteString -> m () Source

An efficient primitive to write a strict ByteString into the output buffer.

In binary this flushes the current buffer, and writes the argument into a new chunk.

putLazyByteString :: ByteString -> m () Source

Write a lazy ByteString efficiently.

With binary, this simply appends the chunks to the output buffer

flush :: m () Source

Pop the ByteString we have constructed so far, if any, yielding a new chunk in the result ByteString.

If we're building a strict ByteString with cereal then this does nothing.

putWord16le :: Word16 -> m () Source

Write a Word16 in little endian format

putWord16be :: Word16 -> m () Source

Write a Word16 in big endian format

putWord16host :: Word16 -> m () Source

O(1). Write a Word16 in native host order and host endianness. For portability issues see putWordhost.

putWord32le :: Word32 -> m () Source

Write a Word32 in little endian format

putWord32be :: Word32 -> m () Source

Write a Word32 in big endian format

putWord32host :: Word32 -> m () Source

O(1). Write a Word32 in native host order and host endianness. For portability issues see putWordhost.

putWord64le :: Word64 -> m () Source

Write a Word64 in little endian format

putWord64be :: Word64 -> m () Source

Write a Word64 in big endian format

putWord64host :: Word64 -> m () Source

O(1). Write a Word64 in native host order and host endianness. For portability issues see putWordhost.

putWordhost :: Word -> m () 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.
