This session we will delve into the sometimes murky world of procedural macros - showing some of the great tooling available for understanding the code generated, such as cargo expand, and the key building blocks we will need for writing our own.
We will cover how to understand what the macros we are calling actually do, as well creating our own very simple derive macros, building up more complex macros using repeat patterns in quote, and looking at basic error reporting.
In this talk, we'll dive deep into what makes concurrency coordination costly, and explore some pathways to mitigate that cost.
This talk puts popular Rust rewrites to the test. We'll examine how these tools stack up against their battle-tested predecessors, looking at real-world performance, compilation times, binary sizes, feature completeness, and ecosystem maturity.
During this talk we'll build a basic, working async runtime using nothing more than a standard library. The point? To see it's approachable for mere mortals.
