Struct rand::distributions::DistMap

pub struct DistMap<D, F, T, S> {
    distr: D,
    func: F,
    phantom: PhantomData<fn(_: T) -> S>,
}

A distribution of values of type S derived from the distribution D by mapping its output of type T through the closure F.

This struct is created by the Distribution::map method. See its documentation for more.

Fields

distr: D

func: F

phantom: PhantomData<fn(_: T) -> S>
