Optional Trait Methods in Rust

An exploration into various ways optional trait methods can be implemented in Rust.

• The complete folder contains a big-blob of example code which shows off the various techniques.
  • The code is a bit of a mess, but it's done to make the outputted assembly as easy to analyze as possible.
    • it's a #![no_std] binary which links with libc
    • doesn't use any of rust's formatting code.
    • makes extensive use of cfg_if to remove any dead code
  • The godbolt.sh script outputs the crate as a single file that can be copy/pasted into godbolt.org
    • godbolt.sh takes two arguments: the Target implementation (i.e: basic, advanced, faulty), and optional trait method implementation (i.e: option, fn, traits).
• writeup.md contains the draft version of a writeup discussing the various techniques
