Map (c :: a -> Exp b) (d :: f a) (e :: f b)first-class-families Fcf Type-level fmap for type-level functors. Note: this name clashes with Map from containers. FMap is provided as a synonym to avoid this.
Example
>>> data Example where Ex :: a -> Example -- Hide the type of examples to avoid brittleness in different GHC versions >>> data AddMul :: Nat -> Nat -> Exp Nat >>> type instance Eval (AddMul x y) = (x TL.+ y) TL.* (x TL.+ y) >>> :kind! Ex (Eval (Map (AddMul 2) '[0, 1, 2, 3, 4]) :: [Nat]) Ex (Eval (Map (AddMul 2) '[0, 1, 2, 3, 4]) :: [Nat]) :: Example = Ex [4, 9, 16, 25, 36]

uniplate Data.Generics.Uniplate.Data.Instances Invariant preserving version of Map from the containers packages, suitable for use with Uniplate. Use toMap to construct values, and fromMap to deconstruct values.

protolude Protolude A Map from keys k to values a. The Semigroup operation for Map is union, which prefers values from the left operand. If m1 maps a key k to a value a1, and m2 maps the same key to a different value a2, then their union m1 <> m2 maps k to a1.
