1//! This module contains types which store a
2//! [`Transformer`] on the heap.  This
3//! is particularly useful to allow for
4//! non-uniform-sized [`Transformer`] types.
5//! The type erasure provided by `dyn` also allows
6//! [`Transformer`]s to be non-uniform in a
7//! collection so long as they implement for the
8//! same generic types.
