Trait naan::apply::ApplyOnce

pub trait ApplyOnce<F, AB>where
    Self: Functor<F, AB>,
    F: HKT1<T<AB> = Self>,{
    // Required method
    fn apply1<A, B>(self, a: F::T<A>) -> F::T<B>
       where AB: F1Once<A, Ret = B>;
}

Apply, but specialized to know at compile-time that the function contained in F will only be called one time.

Required Methods

fn apply1<A, B>(self, a: F::T<A>) -> F::T<B>where AB: F1Once<A, Ret = B>,
