Module doesn't build on ARM target

[mstepien-mobica]

error: cannot produce proc-macro for async-stream-impl v0.3.5 as the target aarch64-unknown-linux-gnu does not support these crate types

I guess this is rust-lang/rust#78210.

This seems to be a problem with the way you tried to compile the code, or with the proc-macro itself, and does not seem to be a problem with this project itself, so I'm going to close this.
