Trait model_mapper::with::NestedWrapper

pub trait NestedWrapper<W: Wrapper<T>, T> {
    type NestedWrapper<U>;

    // Required methods
    fn map_wrapper<Z: Fn(T) -> U, U>(self, f: Z) -> Self::NestedWrapper<U>;
    fn try_map_wrapper<Z: Fn(T) -> Result<U, E>, U, E>(
        self,
        f: Z,
    ) -> Result<Self::NestedWrapper<U>, E>;
}

This type abstracts different kinds of wrappers like Option, Vec, etc. when its value is another Wrapper

Required Associated Types
