Struct DistMap

Source 
pub struct DistMap<D, F, T, S> { /* private fields */ }
Expand description

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.
