Documentation
data Map :: (a -> Exp b) -> f a -> Exp (f b) Source #
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 AddMul :: Nat -> Nat -> Exp Nat
>>>
type instance Eval (AddMul x y) = (x TL.+ y) TL.* (x TL.+ y)
>>>
:kind! Eval (Map (AddMul 2) '[0, 1, 2, 3, 4])
Eval (Map (AddMul 2) '[0, 1, 2, 3, 4]) :: [Nat] = '[4, 9, 16, 25, 36]
