Living with Rust Long-Term - Jon Gjengset

Video Description

Rust and its ecosystem are in constant flux, and this can be scary, especially when you're building an application with stability and long-term project sustainability in mind. New Rust versions bring ever-higher editions, must-have new features, and lint and tool changes to keep on top. And as new features emerge, they'll fade into oblivion. In this talk, we'll look at the changes that may happen to you when working with Rust and how to live with them. We'll talk about Rust and crate versioning, backwards compatibility, unstable features, minimum supported Rust versions, and 1.0 releases. This talk is geared towards those using Rust to build applications and services, not those building Rust libraries. It won't tell you the right way to set up CI for your library crate or decide whether a change is backwards compatible. Instead, we'll dig into the kinds of stability challenges that can arise in Rust, what to do when they crop up, and some promising avenues for making the stable life easier.
