GHC.Types.Unique.DFM

Synopsis

Unique-keyed deterministic mappings

data UniqDFM (key :: k) ele Source #

Type of unique deterministic finite maps

The key is just here to keep us honest. It's always safe to use a single type as key. If two types don't overlap in their uniques it's also safe to index the same map at multiple key types. But this is very much discouraged.

udfmToList :: forall {k} (key :: k) elt. UniqDFM key elt -> [(Unique, elt)] Source #

Converts UniqDFM to a list, with elements in deterministic order. It's O(n log n) while the corresponding function on UniqFM is O(n).

Performs a nondeterministic strict fold over the UniqDFM. It's O(n), same as the corresponding function on UniqFM. If you use this please provide a justification why it doesn't introduce nondeterminism.
