Ganeti.Errors
Description
Implementation of the Ganeti error types.
This module implements our error hierarchy. Currently we implement one identical to the Python one; later we might one to have separate ones for frontend (clients), master and backend code.

saveGanetiException :: GanetiException -> JSValueSource
loadGanetiException :: JSValue -> Result GanetiExceptionSource
type ErrorResult = GenericResult GanetiExceptionSource
Error monad using GanetiException type alias.
excName :: GanetiException -> StringSource
errorExitCode :: GanetiException -> ExitCodeSource
Returns the exit code of a program that should be used if we got back an exception from masterd.
formatError :: GanetiException -> StringSource
Formats an exception.
type ResultG = ResultT GanetiException IOSource
A type for IO actions with errors properly handled as
GanetiExceptions.
TODO: Move to Errors.hs
errToResult :: ErrorResult a -> Result aSource
Convert from an ErrorResult to a standard Result.
maybeToError :: String -> Maybe a -> ErrorResult aSource
Convert from a Maybe to a an ErrorResult.
