Dhall.Binary

Contents

Description

This module contains logic for converting Dhall expressions to and from CBOR expressions which can in turn be converted to and from a binary representation

Synopsis

Standard versions

data StandardVersion Source #

Supported version strings

This exists primarily for backwards compatibility for expressions encoded before Dhall removed version tags from the binary encoding

Constructors

NoVersion

No version string

V_5_0_0

Version "5.0.0"

V_4_0_0

Version "4.0.0"

V_3_0_0

Version "3.0.0"

V_2_0_0

Version "2.0.0"

V_1_0_0

Version "1.0.0"

Encoding and decoding

encodeExpression :: Expr Void Import -> ByteString Source #

Encode a Dhall expression as a CBOR-encoded ByteString

decodeExpression :: Serialise (Expr s a) => ByteString -> Either DecodingFailure (Expr s a) Source #

Decode a Dhall expression from a CBOR Term

Exceptions

newtype DecodingFailure Source #

This indicates that a given CBOR-encoded ByteString did not correspond to a valid Dhall expression
