Does wasapi-rs require nightly?

I've cloned this repository and run cargo run --exapmle playsine. Doing this gave the following error:

   ...

Is wasapi-rs meant to require unstable/nightly, or might this be an error on my side?

I'm using Rust stable v1.59.0.

The latest versions of the windows crate requires nightly if the optional feature for implementing com interfaces is enabled. Since wasapi-rs uses that it means nightly is required here too. They are doing their best to get the things needed stabilized, so expect this to change soon.
See microsoft/windows-rs#1523

Thanks for the reply and the issue link! I'll add that issue to my watch list.

#12
With windows-rs 0.34 the stable compiler can be used as soon as rustc 1.61 is released. Nightly is still needed until then.
