I'd like to discuss about a compiler flag disabling
panic! handling. More precisely,
panic! would expand to a
std::intrinsics::abort, meaning that the whole process exits. Therefore, stack unwinding info would be useless and should not be generated, resulting in a smaller output.
I don't advocate for its systematic use and this is out of discussion.
It is actually the same feature as g++'s
Most functions of the std library are switching from
panic!ing to returning a
Result<>, so they will be usable with this flag. The only field I'm aware of that may stay problematic is memory allocation, I I have no arguments about what to do in this case, I guess aborting would be okay.
