Lol, it took me a while to realize it's the compiler essentially saying "how high".

[-] tempest@lemmy.ca 72 points 10 months ago

I do enjoy the rust compiler error messages. They are nicely formatted

[-] Shameless@lemmy.world 23 points 10 months ago

I'm trying to learn rust and so far this has definitely made it so much more accessible.

Not to mention their super useful "rustlings" training which has these nice little challenges to get you used to language and syntax

[-] 30p87@feddit.de 1 points 10 months ago

Yeah, but to observe such error messages you'll basically need to wait for 20 mins for it to compile.

[-] PlexSheep@infosec.pub 6 points 10 months ago

No? The steps are compiled once and afterwards your project just gets compiled. Besides, rust-analyzer exists.

That's what makes us humans different from computers. We don't ask how high, we just do it. Now, if it were a C pointer it would jump anywhere from 0 to 2^32-1. That's why C is more suited for artificial intelligence than it might initially seem. Thanks for coming to my tedx talk

Pointers are ackshully 48 bits on amd64 (which is most PCs and servers)

I was mostly joking about a stray pointer of type uint32_t*

So the size of the pointer itself doesn't matter

[-] ___qwertz___@feddit.de 5 points 10 months ago

Well ackshully newer CPUs support 5-level-paging which uses 56 bits.

[-] bamfic@lemmy.world 37 points 10 months ago

i dislike rust, but have to give them credit for helpful error messages. not quite racket level but impressive

[-] crispy_kilt@feddit.de 6 points 10 months ago
[-] bamfic@lemmy.world 3 points 10 months ago

the syntax.

[-] Gork@lemm.ee 33 points 10 months ago

WRONG, PRIVATE!

Now drop and give me int(ceil(19.9))!

I don't know Rust but jump typically moves the program counter, where the height represents the number of instructions to move

[-] trxxruraxvr@lemmy.world 14 points 10 months ago

Afaik rust doesn't have functions like that as they lead to unsafe code that's impossible to check variable lifetimes for. I think OP created the jump function.

[-] RustyNova@lemmy.world 14 points 10 months ago

They created it. The compiler says the jump function is in src/main.rs

[-] Klaymore@sh.itjust.works 6 points 10 months ago

It's height in centimeters

[-] fossphi@lemm.ee 4 points 10 months ago

Chad quantised rust

[-] crispy_kilt@feddit.de 2 points 10 months ago

Never use floats.

[-] SatouKazuma@programming.dev 1 points 10 months ago

But then wouldn't it be fly(height: f64) instead of jump(height: i32)?

[-] Darkassassin07@lemmy.ca 3 points 10 months ago

Huh, usually they ask 'jump where?'
