Documentation
data NoDataRuntime Source
The runtime used by queries which retrieve no live data.
Constructors

Generic functions
vTypeToQFT :: VType -> FieldTypeSource
Result helpers
Helper for a result with no data.
rsUnavail :: ResultEntrySource
Helper for result for an entity which supports no such field.
rsNormal :: JSON a => a -> ResultEntrySource
Helper to declare a normal result.
rsMaybeNoData :: JSON a => Maybe a -> ResultEntrySource
Helper to declare a result from a Maybe (the item might be
missing, in which case we return no data). Note that there's some
ambiguity here: in some cases, we mean RSNoData, but in other
RSUnavail; this is easy to solve in simple cases, but not in
nested dicts. If you want to return RSUnavail in case of Nothing
use the function rsMaybeUnavail.
rsErrorNoData :: JSON a => ErrorResult a -> ResultEntrySource
Helper to declare a result from a ErrorResult (an error happened
while retrieving the data from a config, or there was no data).
This function should be used if an error signals there was no data.
rsMaybeUnavail :: JSON a => Maybe a -> ResultEntrySource
Helper to declare a result from a Maybe. This version returns
a RSUnavail in case of Nothing. It should be used for optional
fields that are not set. For cases where Nothing means that there
was an error, consider using rsMaybe instead.
rsUnknown :: ResultEntrySource
Helper for unknown field result.
missingRuntime :: FieldGetter a bSource
Helper for a missing runtime parameter.
Error conversion
rpcErrorToStatus :: RpcError -> ResultStatusSource
Convert RpcError to ResultStatus
Common fields
timeStampFields :: TimeStampObject a => FieldList a bSource
The list of timestamp fields.
uuidFields :: UuidObject a => String -> FieldList a bSource
The list of UUID fields.
serialFields :: SerialNoObject a => String -> FieldList a bSource
The list of serial number fields.
tagsFields :: TagsObject a => FieldList a bSource
The list of tag fields.
Generic parameter functions
dictFieldGetter :: DictObject a => String -> Maybe a -> ResultEntrySource
Returns a field from a (possibly missing) DictObject. This is
used by parameter dictionaries, usually. Note that we have two
levels of maybe: the top level dict might be missing, or one key in
the dictionary might be.
ndParamTypes :: Map String FieldTypeSource
ndParamTitles :: Map String FieldTitleSource
ndParamGetter :: NdParamObject a => String -> ConfigData -> a -> ResultEntrySource
buildNdParamField :: NdParamObject a => String -> FieldData a bSource
Builds the ndparam fields for an object.
beParamTypes :: Map String FieldTypeSource
buildBeParamField :: (String -> ConfigData -> a -> ResultEntry) -> String -> FieldData a bSource
Builds the beparam fields for an object.
hvParamTypes :: Map String FieldTypeSource
buildHvParamField :: (String -> ConfigData -> a -> ResultEntry) -> String -> FieldData a bSource
Builds the beparam fields for an object.
buildParamField :: String -> String -> Map String String -> Map String FieldType -> (String -> ConfigData -> a -> ResultEntry) -> String -> FieldData a bSource
getDefaultHypervisorSpec :: ConfigData -> (Hypervisor, HvParams)Source
Looks up the default hypervisor and its hvparams
getHvParamsFromCluster :: ConfigData -> Hypervisor -> HvParamsSource
Looks up the cluster's hvparams of the given hypervisor
