| > I'm calling bullshit on the every damned thing needs to be DoS or timing-attack hardened But that isn't the claim. Rust's defaults are safe. Remember Rust's one line description "A language empowering everyone to build reliable and efficient software". This is like with the decision that Rust's sort() is a stable sort. I know what a stable sort is, and so do you, so if we care we may decide it's appropriate to use the unstable sort which could be faster. But programmers who don't know what a stable sort is aren't expected to learn about it before their sort does what they expected. Same here, I know that SipHash is slower than Fowler–Noll–Vo, which in turn is slower than the identity function, and I know why it would or would not be OK to choose them, and presumably you do too. So if we care we may choose a different hasher for our HashMap. But programmers who don't know about hash algorithms aren't expected to go learn all this stuff before using HashMap. I think maybe C++ isn't programming it's actually a live action "Um, actually" game where the stakes are your program arbitrarily misbehaves unless you correctly guessed all the things wrong with whatever code you just wrote despite the compiler insisting there's nothing wrong with it as written. Could I do OK at that game? I'd like to think so. Do I want to play? No thanks. |
