Zed Decoded: Async Rust 

This is the first video in a new series, Zed Decoded, in which we'll take a close look at how Zed works and how it's built.
This is the companion video to a full blog post that you can find here 👉 zed.dev/blog/zed-decoded-asyn...
In episode, Thorsten and Antonio talk about async Rust and explore how it's used in Zed. This conversation is the basis for the blog post.
