Description

thought: should we be including this? fuzzing is usually run with debug assertions on so the debug_assert doesn't get us much. I am comfortable with more thoroughly documenting the safety situation instead

Another option is adding a test_assert! macro that is guarded on cfg(test), so it only runs for this crate's tests.

Research direction

Start by reading the discussion from pull request #151 and inventory the crate's existing debug_assert! uses. Compare the tradeoffs of documenting the safety situation versus adding a test_assert! macro guarded by cfg(test). Done means the project has a decided approach and the affected assertions consistently follow it.
