Struct ComposeF 

Source 
pub struct ComposeF<F, G>(/* private fields */);
Expand description

Marker type for the composition of two type constructors: (F . G)(A) = F(G(A)).

Given F: HKT and G: HKT, ComposeF<F, G> is itself an HKT where Of<A> = F::Of<G::Of<A>>.

Trait Implementations§

Source§

impl<F, G> Functor for ComposeF<F, G>
where F: Functor, G: Functor,

Functors compose: if F and G are both Functors, so is F . G.
