Data.Store.Internal

Internal API for the store package. The functions here which are not re-exported by Data.Store are less likely to have stable APIs.

This module also defines most of the included Store instances, for types from the base package and other commonly used packages (bytestring, containers, text, time, etc).

Encoding and decoding strict ByteStrings.

encode :: Store a => a -> ByteString

Serializes a value to a ByteString. In order to do this, it first allocates a ByteString of the correct size (based on size), and then uses poke to fill it.

Safety of this function depends on correctness of the Store instance. If size returns a. The good news is that this isn't an issue if you use well-tested manual instances (such as those from this package) combined with auomatic definition of instances.

decode :: Store a => ByteString -> Either PeekException a

Decodes a value from a ByteString. Returns an exception if there's an error while decoding, or if decoding undershoots / overshoots the end of the buffer.

decodeWith :: Peek a -> ByteString -> Either PeekException a

Decodes a value from a ByteString, potentially throwing exceptions, and taking a Peek to run. It is an exception to not consume all input.

decodeEx :: Store a => ByteString -> a

Decodes a value from a ByteString, potentially throwing exceptions. It is an exception to not consume all input.

decodeExWith :: Peek a -> ByteString -> a

Decodes a value from a ByteString, potentially throwing exceptions, and taking a Peek to run. It is an exception to not consume all input.

decodeExPortionWith :: Peek a -> ByteString -> (Offset, a)

Similar to decodeExWith, but it allows there to be more of the buffer remaining. The Offset of the buffer contents immediately after the decoded value is returned.

decodeIO :: Store a => ByteString -> IO a

Decodes a value from a ByteString, potentially throwing exceptions. It is an exception to not consume all input.

decodeIOWith :: Peek a -> ByteString -> IO a

Decodes a value from a ByteString, potentially throwing exceptions, and taking a Peek to run. It is an exception to not consume all input.

decodeIOPortionWith :: Peek a -> ByteString -> IO (Offset, a)

Similar to decodeExPortionWith, but runs in the IO monad.

Store class and related types.

class Store a where

The Store typeclass provides efficient serialization and deserialization to raw pointer addresses.

The peek and poke methods should be defined such that decodeEx (encode x) == x .

Methods

size :: Size a

Yields the Size of the buffer, in bytes, required to store the encoded representation of the type.

Note that the correctness of this function is crucial for the safety of poke, as it does not do any bounds checking. It is the responsibility of the invoker of poke (encode and similar functions) to ensure that there's enough space in the output buffer. If poke writes beyond, then arbitrary memory can be overwritten, causing undefined behavior and segmentation faults.

poke :: a -> Poke ()

Serializes a value to bytes. It is the responsibility of the caller to ensure that at least the number of bytes required by size are available. These details are handled by encode and similar utilities.

peek :: Peek a

Serialized a value from bytes, throwing exceptions if it encounters invalid data or runs out of input bytes.

size :: (Generic a, GStoreSize (Rep a)) => Size a

Yields the Size of the buffer, in bytes, required to store the encoded representation of the type.

Note that the correctness of this function is crucial for the safety of poke, as it does not do any bounds checking. It is the responsibility of the invoker of poke (encode and similar functions) to ensure that there's enough space in the output buffer. If poke writes beyond, then arbitrary memory can be overwritten, causing undefined behavior and segmentation faults.

poke :: (Generic a, GStorePoke (Rep a)) => a -> Poke ()

Serializes a value to bytes. It is the responsibility of the caller to ensure that at least the number of bytes required by size are available. These details are handled by encode and similar utilities.

peek :: (Generic a, GStorePeek (Rep a)) => Peek a

Serialized a value from bytes, throwing exceptions if it encounters invalid data or runs out of input bytes.

data Poke a :: * -> *

Poke actions are useful for building sequential serializers.

They are actions which write values to bytes into memory specified by a Ptr base. The Applicative and Monad instances make it easy to write serializations, by keeping track of the Offset of the current byte. They allow you to chain Poke action such that subsequent Pokes write into subsequent portions of the output.

data Peek a :: * -> *

Peek actions are useful for building sequential deserializers.

They are actions which read from memory and construct values from it. The Applicative and Monad instances make it easy to chain these together to get more complicated deserializers. This machinery keeps track of the current Ptr and end-of-buffer Ptr.
