Codec.Serialise

Description

This module provides functions to serialise and deserialise Haskell values for storage or transmission, to and from lazy ByteStrings. It also provides a type class and utilities to help you make your types serialisable.

For a full tutorial on using this module, see Codec.Serialise.Tutorial.

Synopsis

High level, one-shot API

The following API exposes a high level interface allowing you to quickly convert between arbitrary Haskell values (which are an instance of Serialise) and lazy ByteStrings.

serialise :: Serialise a => a -> ByteString Source #

Serialise a Haskell value to an external binary representation.

The output is represented as a lazy ByteString and is constructed incrementally.

Since: 0.2.0.0

deserialise :: Serialise a => ByteString -> a Source #

Deserialise a Haskell value from the external binary representation (which must have been made using serialise or related function).

Throws: DeserialiseFailure if the given external representation is invalid or does not correspond to a value of the expected type.

Since: 0.2.0.0

deserialiseOrFail :: Serialise a => ByteString -> Either DeserialiseFailure a Source #

Deserialise a Haskell value from the external binary representation, or get back a DeserialiseFailure.

Since: 0.2.0.0

Deserialisation exceptions

data DeserialiseFailure #

An exception type that may be returned (by pure functions) or thrown (by IO actions) that fail to deserialise a given input.

Since: cborg-0.2.0.0

Incremental encoding interface

The following API allows you to encode or decode CBOR values incrementally, which is useful for large structures that require you to stream values in over time.

serialiseIncremental :: Serialise a => a -> Builder Source #

Serialise a Haskell value to an external binary representation.

The output is represented as a Builder and is constructed incrementally. The representation as a Builder allows efficient concatenation with other data.

Since: 0.2.0.0

deserialiseIncremental :: Serialise a => ST s (IDecode s a) Source #

Deserialise a Haskell value from the external binary representation.

This allows input data to be provided incrementally, rather than all in one go. It also gives an explicit representation of deserialisation errors.

Note that the incremental behaviour is only for the input data, not the output value: the final deserialised value is constructed and returned as a whole, not incrementally.

Since: 0.2.0.0

data IDecode s a #

An Incremental decoder, used to represent the result of attempting to run a decoder over a given input, and return a value of type a.

Constructors

Partial (Maybe ByteString -> ST s (IDecode s a))

The decoder has consumed the available input and needs more to continue. Provide Just if more input is available and Nothing otherwise, and you will get a new IDecode.

Done !ByteString !ByteOffset a

The decoder has successfully finished. Except for the output value you also get any unused input as well as the number of bytes consumed.

Fail !ByteString !ByteOffset DeserialiseFailure

The decoder ran into an error. The decoder either used fail or was not provided enough input. Contains any unconsumed input, the number of bytes consumed, and a DeserialiseFailure exception describing the reason why the failure occurred.

The Serialise class

class Serialise a where Source #

Types that are instances of the Serialise class allow values to be quickly encoded or decoded directly to a CBOR representation, for object transmission or storage.

Since: 0.2.0.0

IO operations

Convenient utilities for basic IO operations.

FilePath API

writeFileSerialise Source #

Arguments

:: Serialise a 
=> FilePath

The file to write to.

-> a

The value to be serialised and written.

-> IO () 

Serialise a ByteString and write it directly to the specified file.

Since: 0.2.0.0

readFileDeserialise Source #

Arguments

:: Serialise a 
=> FilePath

The file to read from.

-> IO a

The deserialised value.

Read the specified file (internally, by reading a ByteString) and attempt to decode it into a Haskell value using deserialise (the type of which is determined by the choice of the result type).

Throws: DeserialiseFailure if the file fails to deserialise properly.

Since: 0.2.0.0

Handle API

hPutSerialise Source #

Arguments

:: Serialise a 
=> Handle

The Handle to write to.

-> a

The value to be serialised and written.

-> IO () 

Serialise a ByteString (via serialise) and write it directly to the specified Handle.

Since: 0.2.0.0
