@ c4

Join us on Wednesday, December 4, 2019 at the C4 to celebrate the coming and of the year and the advent of async/await in Rust!

Shortly after our last meetup Rust 1.39 was released as the first release to support async and .await syntax. This was the last step towards convenient asynchronous programming in stable Rust.

To celebrate we’ll have glühwein as well as other hot and cold beverages. There will also be a short talk introducing async/await in some detail.

We are looking forward to seeing you!

Yours, Florian

The meetup will likely be held in German, we will however reevaluate this at the beginning of the evening and may switch to English if needed.

  1. The async Rust ecosystem

    Rust 1.36 introduced a stable version of the Future trait into libstd. Now Rust 1.39 has introduced stable async fn and .await syntax making use of the Future trait easy and convenient. Traits and syntaxes aren’t useful on their own though. We still need implementations and users. This talk will give an introduce how concepts like Future, async, await, executors, etc. work together and provide a quick overview of the existing ecosystem.

Location: Chaos Computer Club Cologne (c4) e.V.
