Query
null ∷ InvertedMap v k → Bool Source #
Construction
toMap ∷ Ord k ⇒ InvertedMap v k → Map k v Source #
This inverts the given InvertedMap
Inversion is an https://en.wikipedia.org/wiki/Involution_(mathematics), so
this returns to Map.
unsafeInvertedMap ∷ Map v (NonEmpty k) → InvertedMap v k Source #
Conversion
unsafeCoercion ∷ Coercion (InvertedMap v k) (Map v (NonEmpty k)) Source #
Filter
spanAntitone ∷ (v → Bool) → InvertedMap v k → (InvertedMap v k, InvertedMap v k) Source #
Min/Max
minViewWithKey ∷ InvertedMap v k → Maybe ((v, NonEmpty k), InvertedMap v k) Source #
