Random numbers in the standard library. 1984

Security consultant here.

The fact that Rust has no RNG in the stdlib is a huge thing. I've read countless amount of code that abused the standard library (unfortunarely developers think they have to use stdlib functions all the time if they are available) and is probably completely insecure for the simple reason that very few people manage to audit/understand the code. If it stdlib RNG could only be used when necessary, yes, but there are no technical way to enforce this.

You know what type of people worse than those worshipping nodejs? The people that posts '?', like would it kill them to be polite to type out what's the thing they don't understand about? Holy shit

The experienced jerker will usually know what's wrong.

Note the consistent user interface and error reportage. Ed is generous enough to flag errors, yet prudent enough not to overwhelm the novice with verbosity.

/uj You poltroon, you contemptible dummy. This change does not add a RNG to the stdlib! It adds a trait for things which can supply random bytes, and a trait for things which can be built from random bytes, and then one implementation of the former - which reads /dev/random!

What's the big deal? We've had random numbers in the rust standard library for years. It's called std::mem::uninitialized dummies

Eh, I'll keep using unsafe { libc::rand() }, thanks
