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

[–] tempest@lemmy.ca 70 points 5 months ago (2 children)

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

[–] Shameless@lemmy.world 22 points 5 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 5 months ago (1 children)

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

[–] PlexSheep@infosec.pub 5 points 5 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)

[–] ___qwertz___@feddit.de 5 points 5 months ago

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

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

So the size of the pointer itself doesn't matter

[–] bamfic@lemmy.world 37 points 5 months ago (1 children)

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

[–] crispy_kilt@feddit.de 5 points 5 months ago (1 children)

What made you dislike it?

[–] bamfic@lemmy.world 3 points 5 months ago

the syntax.

[–] Gork@lemm.ee 33 points 5 months ago

WRONG, PRIVATE!

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

[–] trxxruraxvr@lemmy.world 11 points 5 months ago (5 children)

Height should be a float

[–] ParanoiaComplex@lemmy.world 9 points 5 months ago* (last edited 5 months ago) (1 children)

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 5 months ago (1 children)

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 5 months ago

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

[–] Klaymore@sh.itjust.works 6 points 5 months ago (1 children)

It's height in centimeters

[–] fossphi@lemm.ee 4 points 5 months ago

Chad quantised rust

[–] SatouKazuma@programming.dev 1 points 5 months ago

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

[–] crispy_kilt@feddit.de 1 points 5 months ago

Never use floats.

[–] Darkassassin07@lemmy.ca 3 points 5 months ago

Huh, usually they ask 'jump where?'
