A case for CancellationTokens

A case for CancellationTokens

Background

The Rust async working group is currently actively discusing on ways to improve async/await. Niko Matsakis documented the main goals and ideas in the async vision document.

As part of the improved async ecosytem, users should be able to make use of

Async/Await - The challenges besides syntax - Cancellation

Async/Await - The challenges besides syntax - Cancellation

This is the second article in a series of articles around Rusts new async/await feature. The first article about interfaces can be found here.

In this part of the series we want to a look at a mechanism which behaves very different in Rust than in all other languages which feature async/await support. This mechanism is Cancellation.

# Async/Await - The challenges besides syntax

Async/Await - The challenges besides syntax

4 years after after the release of Rust 1.0, it seems like Rust is now finally getting close to getting support for async/await - a language feature which aims to make it easier to write programs in an asynchronous fashion (where multiple logical tasks get multiplexed on a lower number of OS threads).

One of the last steps before the feature is stabilized is choosing the best possible syntax. The discussions around syntax have triggered an enormous
