inconceivable

inconceivable! is a macro which closely parallels std::unreachable, or std::panic. The primary difference is that when this crate is configured with the ub_inconceivable option it will emit the core::hint::unreachable_unchecked to hint for the compiler to understand a condition should never occur.

Generally compiler(s) (the LLVM) assume UB won't happen. This macro offers the "best of both worlds", it provides a solid way of asserting/testing behavior in local builds, but also a way of stripping branches out of final release builds.

Please Note: This crate is created purely to inject undefined behavior into stable, safe rust. Systematic usage is unwise, and not recommended.
