Trait Apply

Source 
pub trait Apply<A, F, B>: Functor<A, B> + Lift3<A, F, B>
where
    F: Fn(A) -> B,
{
    // Required method
    fn apply(
        self,
        f: <Self as Lift3<A, F, B>>::Target2,
    ) -> <Self as Lift<A, B>>::Target1;
}
Expand description

Apply takes an F<Fn(A) -> B> and applies it to an F<A> to produce an F<B>.

Required Methods§

Source

fn apply( self, f: <Self as Lift3<A, F, B>>::Target2, ) -> <Self as Lift<A, B>>::Target1

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
