StableName of a (c (Full a)) with hidden result type

Constructors

StName :: StableName (c (Full a)) -> StName c

Instances

Eq (StName c)

hash :: StName c -> Int Source

type History c = IntMap [(StName c, NodeId)]Source

A hash table from StName to NodeId (with hash as the hashing function). I.e. it is assumed that the StNames at each entry all have the same hash, and that this number is equal to the entry's key.

lookHistory :: History c -> StName c -> Maybe NodeId Source

Lookup a name in the history

remember :: StName c -> NodeId -> History c -> History cSource

Insert the name into the history

fresh :: (Enum a, MonadIO m) => IORef a -> m aSource

Return a fresh identifier from the given supply
