Trait Implementations§

Source§

impl Bifunctor<Tuple2Witness> for Tuple2Witness

Source§

fn bimap<A, B, C, D, F1, F2>(fab: (A, B), f1: F1, f2: F2) -> (C, D)
where F1: FnMut(A) -> C, F2: FnMut(B) -> D,

Maps both types simultaneously. Read more
Source§

fn first<A, B, C, F1>(fab: F::Type<A, B>, f1: F1) -> F::Type<C, B>
where F1: FnMut(A) -> C,

Maps only the first type parameter. Equivalent to bimap(f, id).
Source§

fn second<A, B, D, F2>(fab: F::Type<A, B>, f2: F2) -> F::Type<A, D>
where F2: FnMut(B) -> D,

Maps only the second type parameter. Equivalent to bimap(id, g).
Source§

impl HKT2Unbound for Tuple2Witness

Source§

type Type<A, B> = (A, B)

The Generic Associated Type representing F<A, B>
