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

Constructors

CryptoPassed a
CryptoFailed CryptoError

throwCryptoErrorIO :: CryptoFailable a -> IO a Source #

Throw an CryptoError as exception on CryptoFailed result, otherwise return the computed value

throwCryptoError :: CryptoFailable a -> a Source #

Same as throwCryptoErrorIO but throw the error asynchronously.

onCryptoFailure :: (CryptoError -> r) -> (a -> r) -> CryptoFailable a -> r Source #

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
