`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
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.
