Description

Implementation of the Ganeti network objects.

This is does not (yet) cover all methods that are provided in the corresponding python implementation (network.py).

Documentation

data PoolPart #

Constructors

PoolInstances
PoolExt

netIpv4NumHosts :: Network -> Integer #

ip4BaseAddr :: Ip4Network -> Ip4Address #

getReservedCount :: Network -> Int #

Get the count of reserved addresses.

getFreeCount :: Network -> Int #

Get the count of free addresses.

isFull :: Network -> Bool #

Check whether the network is full.

getMap :: Network -> String #

Return a textual representation of the network's occupation status.

isReserved :: (MonadError e m, Error e) => PoolPart -> Ip4Address -> Network -> m Bool #

Checks if a given address is reserved. Fails if the address isn't in the network range.

reserve :: (MonadError e m, Error e) => PoolPart -> Ip4Address -> Network -> m Network #

Marks an address as used.

release :: (MonadError e m, Error e) => PoolPart -> Ip4Address -> Network -> m Network #

Marks an address as unused.

findFree :: (MonadError e m, Error e) => (Ip4Address -> Bool) -> Network -> m (Maybe Ip4Address) #

Get the first free address in the network that satisfies a given predicate.

allReservations :: Network -> Maybe BitArray #

Get a bit vector of all reservations (internal and external) combined.

reservations :: Network -> Maybe BitArray #

extReservations :: Network -> Maybe BitArray #
