Welcome to the Rust Edition Guide! "Editions" are Rust's way of communicating large changes in the way that it feels to write Rust code.
In this guide, we'll discuss:
- What editions are
- What each edition is about
- How to migrate your code from one edition to another
Note that the standard library grows with each Rust release; there are many additions to the standard library that are not called out in this guide. Only the major ones are, but there's tons of medium and small things that are great too. You may want to check out the standard library documentation as well.
