Summary
Library exclusively intended to inject UB into safe Rust.
Details

Quoting from the crate description:

This crate is created purely to inject undefined behavior into stable, safe rust.

Specifically, the inconceivable! macro is insta-UB if the ub_inconceivable feature is enabled by any reverse dependency. The value this adds is questionable, and hides unsafe code from naive analysis.
