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 -> JSValue Source #

loadGanetiException :: JSValue -> Result GanetiException Source #

type ErrorResult = GenericResult GanetiException Source #

Error monad using GanetiException type alias.

excName :: GanetiException -> String Source #

errorExitCode :: GanetiException -> ExitCode Source #

Returns the exit code of a program that should be used if we got back an exception from masterd.

formatError :: GanetiException -> String Source #

Formats an exception.

type ResultG = ResultT GanetiException IO Source #

A type for IO actions with errors properly handled as GanetiExceptions. TODO: Move to Errors.hs

errToResult :: ErrorResult a -> Result a Source #

Convert from an ErrorResult to a standard Result.

maybeToError :: String -> Maybe a -> ErrorResult a Source #

Convert from a Maybe to a an ErrorResult.
