When you need to get the asynchronous out of the way.

Corona is a library providing stackful coroutines for Rust. They integrate well with futures ‒ it is possible to switch between the abstractions as needed, each coroutine is also a future and a coroutine can wait for a future to complete. Furthermore, the futures don't have to be 'static.

On the other hand, there's a runtime cost to the library. The performance does not necessarily suffer (that yet needs to be measured, but the fact a future doesn't need to own its data may actually make it faster). But each coroutine has its own stack, which takes memory.

You want to read the docs and examine the examples.

I hope to stabilize the API soon. But I want to write some more examples and experiments first.

If you use it for something, I want to hear about it.
