Rust compiled in debug mode

[Ithinuel]

Do you have any real example of these code that currently work in rust’s debug mode that would not in release mode ?

Aside from panic the behaviour is meant to be the very same. The only actual difference being the execution speed.
Some extra check are disabled in release mode that would panic in debug mode (such as overflow/wrapping).
So the actual argument would be :

if we change the command line, many new code would work while they wouldn’t have before

EDIT:
I remembered a discussion about that last year :

At the moment, every languages on CG are compiled/run without optimization flag (debug purpose > time). Plus, we don’t keep “stuff” around: you work on a new environnement each play.

But, it may change since we’re rebuilding our infra for the Learning project and some ideas might be reuse for the puzzles.

That thing about debug purposes makes sense though.
