-// FIXME: Currently RingBuffer requires its type parameter to be
-// `Copy` because items are stored in a fixed-length array (which,
-// itself, is required to allow creating RingBuffers
-// statically). There may be work-arounds with ptr routines, and it
-// should be investigated.
+//! An implementation of STAtically allocated Ring Buffers.
+//!
+//! This is a simple ring-buffer structure that lives on the stack,
+//! rather than the heap, so that it can be used in `no-std`
