data CryptoFailable a Source #

A simple Either like type to represent a computation that can fail

2 possibles values are:

  • CryptoPassed : The computation succeeded, and contains the result of the computation
  • CryptoFailed : The computation failed, and contains the cryptographic error associated

Simple either like combinator for CryptoFailable type

eitherCryptoError :: CryptoFailable a -> Either CryptoError a Source #

Transform a CryptoFailable to an Either

maybeCryptoError :: CryptoFailable a -> Maybe a Source #

Transform a CryptoFailable to a Maybe
