RustLatam 2019 - Alex Crichton: Procedural Macros vs Sliced Bread

Alex will try to convince us that procedural macros are the best thing since sliced bread. With "macros 1.2" now on stable Rust there's no better time to discover the world of procedural macros and what they can do for us.

We've already seen the power of derive macros shoot Serde to one of the most popular crates in Rust. With attribute macros we can go even further with lightweight annotations powering frameworks. And finally with procedural macros the sky is the limit!

Let's learn about tips, tricks, and usage of the procedural macro world!

Love Alex's talks because I don't need not even 1.25x to listen.

(The audio echo was a little distracting, which is a shame because it was a good succinct talk.)

Massively cool. I always like to explore the metaprogramming capabilities of the computer languages I know, and so far, Rust comes way out ahead.

[UberOcelot]

Is that an echo, or is that a translator? Bit distracting but great talk.

25:40 Very cool. Ironic that "procedural" macros are one of Rust's best tools for declarative programming!
