Devconf.cz 2023

This talk will focus primarily on Rust with some comparisons to other modern programming languages like Go to give a deep dive into Rust asynchronous programming from a user's perspective. On our team at Red Hat, we migrated from a synchronous, single-threaded application to an asynchronous, multithreaded paradigm. This talk will primarily focus on three separate aspects of asynchronous programming in Rust. We'll discuss the state of the world for asynchronous programming as it stands now, the syntax and basic implementation of asynchronous programming and why this matters, and a short case study of implementing a low level synchronization lock for multithreaded programming and what problems we bumped into while implementing it. This talk will hopefully give you the building blocks to work with the complex ecosystem of asynchronous Rust while avoiding common problems that often cause issues like deadlocks, compilation errors, and subtle bugs for newcomers.
