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

Constructors

V_4_0_0

Version "4.0.0"

defaultStandardVersion :: StandardVersion Source #

parseStandardVersion :: Parser StandardVersion Source #

Encoding and decoding

encodeWithVersion :: StandardVersion -> Expr s Import -> Term Source #

Encode a Dhall expression using the specified Version

decodeWithVersion :: Term -> Either DecodingFailure (Expr s Import) Source #

Decode a Dhall expression

This auto-detects which standard version to decode based on the included standard version string in the decoded expression

Exceptions

data DecodingFailure Source #

Constructors

CannotDecodeVersionString Term
UnsupportedVersionString Text
CBORIsNotDhall Term
