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

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

Shameless@lemmy.world · 22 pts · 2y

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

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)

embed_me@programming.dev · 5 pts · 2y

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 pts · 2y

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

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

crispy_kilt@feddit.de · 6 pts · 2y (1 reply)

What made you dislike it?

bamfic@lemmy.world · 3 pts · 2y

the syntax.

Gork@lemm.ee · 32 pts · 2y

WRONG, PRIVATE!

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

Height should be a float

ParanoiaComplex@lemmy.world · 10 pts · 2y (2 replies)

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 pts · 2y (1 reply)

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 pts · 2y

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

Klaymore@sh.itjust.works · 6 pts · 2y (1 reply)

It's height in centimeters

Chad quantised rust

crispy_kilt@feddit.de · 2 pts · 2y

Never use floats.

SatouKazuma@programming.dev · 1 pts · 2y

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

Darkassassin07@lemmy.ca · 3 pts · 2y

Huh, usually they ask 'jump where?'
