@SteveLauC excellent work, @bconn98 thanks for reviewing this.

@SteveLauC can you write some super simple tests just verifying in debug and release mode things work as expected?

[SteveLauC]

Test added, commits squashed

Code formatted

Gentle ping on @bconn98 and @estk, PTAL

[bconn98]

Quick check from mobile and kicking off the tests on my build server look good 👍🏻

[estk]

Lgtm with one exception, we need to build and run this test in CI. Maybe add another line to the Test action that does a 'cargo test --release --features simple_writer yourtestfile -- yourtestname'

[SteveLauC]

I recommend enabling CI even for first-time-contributors so that we can check if it works as expected

@SteveLauC Branch is out of date
