Dhall.Binary

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

Standard versions

data StandardVersion

Supported version strings

Constructors

V_4_0_0

Version "4.0.0"

defaultStandardVersion :: StandardVersion

parseStandardVersion :: Parser StandardVersion

Encoding and decoding

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

Encode a Dhall expression using the specified Version

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

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

Constructors

CannotDecodeVersionString Term

UnsupportedVersionString Text

CBORIsNotDhall Term
