Help text

Controls how `build_error!` and `build_assert!` are handled during the build.

If calls to them exist in the binary, it may indicate a violated invariant or that the optimizer failed to verify the invariant during compilation.

This should not happen, thus by default the build is aborted. However, as an escape hatch, you can choose Y here to ignore them during build and let the check be carried at runtime (with `panic!` being called if the check fails).

If unsure, say N.
