Trait model_mapper::with::Wrapper

pub trait Wrapper<T> {
    type Wrapper<U>;

    // Required methods
    fn map_inner<Z: Fn(T) -> U, U>(self, f: Z) -> Self::Wrapper<U>;
    fn try_map_inner<Z: Fn(T) -> Result<U, E>, U, E>(
        self,
        f: Z,
    ) -> Result<Self::Wrapper<U>, E>;
}

This type abstracts different kinds of wrappers like Option, Vec, etc.
