data CryptoFailable a

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

Constructors

CryptoPassed a

CryptoFailed CryptoError

Simple either like combinator for CryptoFailable type

eitherCryptoError :: CryptoFailable a -> Either CryptoError a

Transform a CryptoFailable to an Either
