 The purpose of this post is to document the high-level structure and the relevant interfaces that come into play on the Rust side of this.
 The actual mechanism of unwinding is a totally different matter (and one that I am not qualified to speak about).

+Many of the interfaces described here are unstable internal details of libstd, and subject to change any time.
